Overview

Python Spatial Analysis Library

PySAL, the Python spatial analysis library, is an open source cross-platform library for geospatial data science with an emphasis on geospatial vector data written in Python. It supports the development of high level applications for spatial analysis, such as

detection of spatial clusters, hot-spots, and outliers
construction of graphs from spatial data
spatial regression and statistical modeling on geographically embedded networks
spatial econometrics
exploratory spatio-temporal data analysis

PySAL Components

PySAL is a family of packages for spatial data science and is divided into four major components:

Lib

solve a wide variety of computational geometry problems including graph construction from polygonal lattices, lines, and points, construction and interactive editing of spatial weights matrices & graphs - computation of alpha shapes, spatial indices, and spatial-topological relationships, and reading and writing of sparse graph data, as well as pure python readers of spatial vector data. Unike other PySAL modules, these functions are exposed together as a single package.

libpysal : libpysal provides foundational algorithms and data structures that support the rest of the library. This currently includes the following modules: input/output (io), which provides readers and writers for common geospatial file formats; weights (weights), which provides the main class to store spatial weights matrices, as well as several utilities to manipulate and operate on them; computational geometry (cg), with several algorithms, such as Voronoi tessellations or alpha shapes that efficiently process geometric shapes; and an additional module with example data sets (examples).

Explore

The explore layer includes modules to conduct exploratory analysis of spatial and spatio-temporal data. At a high level, packages in explore are focused on enabling the user to better understand patterns in the data and suggest new interesting questions rather than answer existing ones. They include methods to characterize the structure of spatial distributions (either on networks, in continuous space, or on polygonal lattices). In addition, this domain offers methods to examine the dynamics of these distributions, such as how their composition or spatial extent changes over time.

esda : esda implements methods for the analysis of both global (map-wide) and local (focal) spatial autocorrelation, for both continuous and binary data. In addition, the package increasingly offers cutting-edge statistics about boundary strength and measures of aggregation error in statistical analyses
giddy : giddy is an extension of esda to spatio-temporal data. The package hosts state-of-the-art methods that explicitly consider the role of space in the dynamics of distributions over time
inequality : inequality provides indices for measuring inequality over space and time. These comprise classic measures such as the Theil T information index and the Gini index in mean deviation form; but also spatially-explicit measures that incorporate the location and spatial configuration of observations in the calculation of inequality measures.
pointpats : pointpats supports the statistical analysis of point data, including methods to characterize the spatial structure of an observed point pattern: a collection of locations where some phenomena of interest have been recorded. This includes measures of centrography which provide overall geometric summaries of the point pattern, including central tendency, dispersion, intensity, and extent.
segregation : segregation package calculates over 40 different segregation indices and provides a suite of additional features for measurement, visualization, and hypothesis testing that together represent the state-of-the-art in quantitative segregation analysis.
spaghetti : spaghetti supports the the spatial analysis of graphs, networks, topology, and inference. It includes functionality for the statistical testing of clusters on networks, a robust all-to-all Dijkstra shortest path algorithm with multiprocessing functionality, and high-performance geometric and spatial computations using geopandas that are necessary for high-resolution interpolation along networks, and the ability to connect near-network observations onto the network

Model

In contrast to explore, the model layer focuses on confirmatory analysis. In particular, its packages focus on the estimation of spatial relationships in data with a variety of linear, generalized-linear, generalized-additive, nonlinear, multi-level, and local regression models.

mgwr : mgwr provides scalable algorithms for estimation, inference, and prediction using single- and multi-scale geographically-weighted regression models in a variety of generalized linear model frameworks, as well model diagnostics tools
spglm : spglm implements a set of generalized linear regression techniques, including Gaussian, Poisson, and Logistic regression, that allow for sparse matrix operations in their computation and estimation to lower memory overhead and decreased computation time.
spint : spint provides a collection of tools to study spatial interaction processes and analyze spatial interaction data. It includes functionality to facilitate the calibration and interpretation of a family of gravity-type spatial interaction models, including those with production constraints, attraction constraints, or a combination of the two.
spreg : spreg supports the estimation of classic and spatial econometric models. Currently it contains methods for estimating standard Ordinary Least Squares (OLS), Two Stage Least Squares (2SLS) and Seemingly Unrelated Regressions (SUR), in addition to various tests of homokestadicity, normality, spatial randomness, and different types of spatial autocorrelation. It also includes a suite of tests for spatial dependence in models with binary dependent variables.
spvcm : spvcm provides a general framework for estimating spatially-correlated variance components models. This class of models allows for spatial dependence in the variance components, so that nearby groups may affect one another. It also also provides a general-purpose framework for estimating models using Gibbs sampling in Python, accelerated by the numba package.
tobler : tobler provides functionality for for areal interpolation and dasymetric mapping. Its name is an homage to the legendary geographer Waldo Tobler a pioneer of dozens of spatial analytical methods. tobler includes functionality for interpolating data using area-weighted approaches, regression model-based approaches that leverage remotely-sensed raster data as auxiliary information, and hybrid approaches.
access : access aims to make it easy for analysis to calculate measures of spatial accessibility. This work has traditionally had two challenges: [1] to calculate accurate travel time matrices at scale and [2] to derive measures of access using the travel times and supply and demand locations. access implements classic spatial access models, allowing easy comparison of methodologies and assumptions.
spopt: spopt is an open-source Python library for solving optimization problems with spatial data. Originating from the original region module in PySAL, it is under active development for the inclusion of newly proposed models and methods for regionalization, facility location, and transportation-oriented solutions.

Viz

The viz layer provides functionality to support the creation of geovisualisations and visual representations of outputs from a variety of spatial analyses. Visualization plays a central role in modern spatial/geographic data science. Current packages provide classification methods for choropleth mapping and a common API for linking PySAL outputs to visualization tool-kits in the Python ecosystem.

legendgram : legendgram is a small package that provides "legendgrams" legends that visualize the distribution of observations by color in a given map. These distributional visualizations for map classification schemes assist in analytical cartography and spatial data visualization
mapclassify : mapclassify provides functionality for Choropleth map classification. Currently, fifteen different classification schemes are available, including a highly-optimized implementation of Fisher-Jenks optimal classification. Each scheme inherits a common structure that ensures computations are scalable and supports applications in streaming contexts.
splot : splot provides statistical visualizations for spatial analysis. It methods for visualizing global and local spatial autocorrelation (through Moran scatterplots and cluster maps), temporal analysis of cluster dynamics (through heatmaps and rose diagrams), and multivariate choropleth mapping (through value-by-alpha maps. A high level API supports the creation of publication-ready visualizations

Installation

Comments

Geotable plot

This is a PR to bring into pysal/dev work to implement easy plotting for geotables. Not to be merged yet but rather to create a place to centralized the discussion around design details and so on. My idea is that, once we're happy with it we merge and, ideally, we have it in by the time @ljwolf's GSoC project gets merged as well so we can have a big splash on simplifying workflows with spatial data.

So far, this implements basic machinery to plot geotables with both a matplotlib and a bokeh backend and contains a color.py module with palette support that depends on bewer2mpl. There's a notebook (geotable_plot) explaining the new functionality.

Approximate spatial weights for barely-touching polygons

Hi, I have some problems with this code:

Question

Enum links around regions hangs
Enumerating the links around region 2 hangs. This is likely due to the filaments in that region.

To reproduce:

file_name = "streets_net.shp" coords, edges = net_shp_io.reader(file_name, doubleEdges=True) wed_streets = wed.extract_wed(edges, coords) wed_streets.region_edge[2] wed.enum_edges_region(wed_streets,2)

This region is keyed to edge (33,34) which is the SW corner edge. The link that causes the hang is (136, 198).

wed.regions_from_graph is correctly identifying both the filaments (3) and the regions. Minimal cycle 2, that becomes region 2 in the WED is: [34, 33, 153, 159, 158, 157, 156, 177, 134, 132, 133, 196, 141, 143, 135, 136, 35, 34]

Therefore, I would guess the issue is occurring somewhere in the generation of one of the WED pointers. Best guess is the start and end link pointers.

Wiki page http://code.google.com/p/pysal/wiki/Installation still shows dependencies that we are out of date and lacks specificity on versions for numpy and scipy

It should mirror what is on the pysal.org http://pysal.org/users/installation.html page so the two are in sync

ML Lag indexing error on optimization result
When running ml_lag, I get the following error: IndexError: invalid index to scalar variable. This is from the code: self.rho = res.x[0][0]. I went into the ml_lag.py file in spreg and printed out res, which is the OptimizeResult object from scipy. This was the following output:

status: 0 nfev: 36 success: True fun: array([[ nan]]) x: -0.23606797749978981 message: 'Solution found.'

X should be a solution array, but here it is just a scalar value. I changed rho = res.x[0][0] to rho=res.x; however, that gave me problems elsewhere.

PySAL 2.1.0 changing matplotlib backend (Jupyter)
I've encountered an issue with PySAL 2.1.0 (possibly conda specific?) in which importing pysal into a Jupyter notebook changes the matplotlib rendering back-end from whatever I specify (TkAgg) to agg, which doesn't work and yields the error:

ipykernel_launcher.py:12: UserWarning: Matplotlib is currently using agg, which is a non-GUI backend, so cannot show the figure. if sys.path[0] == '':

The attached screenshot shows this behaviour in action in a notebook (I've also attached the notebook for testing purposes, though you'll need to change the extension back to .ipynb).

I've confirmed that this issue is specific to 2.1.0 by downgrading to 2.0.0 and the issue disappears (see second attached screenshot). Perhaps this is something specific to Jupyter/JupyterLab but the fact that downgrading PySAL makes the problem go away leaves me wondering...

jon

P.S. Can supply a full Conda YAML file if necessary, but this should be easily reproducible if it's actually something specific to PySAL 2.1.0.

Documentation Clarification Help
Hello,

I have two questions:

If you want to integrate your own package with pysal, which has it's own geometry objects, what suggestions do you suggest in order to make the geometries inter-operable? Do I just need to provide a __geo_interface__ property on my geometry object?

The help is very quick to mention how to use geopandas with this package. How do you actually use a geopandas' dataframe with pysal? Are there any examples of doing this? How do you create a w from a geopandas dataframe?

GSOC -SpInt
This PR is to promote review and discussion of what I have produced as a result of my Google Summer of Code project, which was to develop code for spatial interaction modeling and the general analysis of spatial interaction data.

A list of the current features, and future work is here and an in-depth log of the project development can be found on the project blog. A jupyter notebook that showcases the use of the main features is here.

Some potential points of discussion:

The CountModel class: originally meant to act as a dispatcher to different types of count models and estimation techniques, it currently only dispatched to Poisson models estimated using IWLS, which makes it sort of superficial. If support for more models/estimation techniques are added then this might become more useful. If non-count models (i.e., Gaussian) are added, perhaps a better name reflective of this flexibility should be chosen.

VecMoran class: right now this class relies on list comprehensions to store the output of permutations. For large datasets, the memory overheard becomes huge, so perhaps there is a better way to store only the necessary output rather than say, the entire W object for each permutation. This problem does not arise in a regular Moran's I because the permutation does not effect the spatial organization of the spatial units as it does in the vector-based Moran's I.

OD based weights: the ODW type spatial weight, which is based on the contiguity of both origins and destinations, currently takes in an n x n origin W and and n x n destination W (often these are the same) and returns the n**2 x n**2 origin-destination W. It might be useful, depending on how development of a SAR Lag spatial interaction model goes, to have it also return n**2 x n**2 W's for the origins and destinations too. These are just the result of np.kron(np.identity(n), originW) and np.kron(destinationW, np.identity(n)) and are needed to have W objects that match the dimensions of the n x 1 vector of spatial interaction observations. This point overlaps with #847

Default intercept behavior: currently the spatial interaction models are calibrated without intercepts. This can be changed using the boolean parameter constant=True. I found that the intercept needs to be omitted for the results to match those calibrated from maximum entropy and maximum likelihood estimation, though this default behavior might not always be optimal.

GSoC 2022 Interfaces for Consistent API Design: Library-wide Discussion
For GSoC 2022, I'm working on designing more consistent interfaces to PySAL's exploratory and inferential statistics classes. The end goal is to design a sleek new API for PySAL's statistical classes that is highly self-consistent.

To couple with related issues in spreg, mgwr, esda, spopt, and spglm, I'm creating an issue here for discussion on library-wide concerns related to this project. From discussion in the other issues, it seems like a PySAL-specific set of base classes would be most preferable to developers. While scikit-learn and multiple dispatch might not be great fits for the library, it still needs consistent standards (whether or not they conform to external rules). Creating a PySAL-specific framework would have several key advantages, like in-house maintainability and customizability.

Importantly, I'm starting this API redesign in the modeling classes (spreg first, then likely moving to mgwr, spint, and beyond). Developing common constructs for these packages is a good subproblem before moving out of the model module. To this end, I'm interested in getting your feedback on the following questions:

What design elements would you like to see implemented in a new interface for PySAL's modeling classes?

What design elements does PySAL's current design get right, and what design elements could be deprecated?

Are there library/package/code structures elsewhere that might be beneficial to use or mimic in PySAL? What benefits would PySAL gain from drawing on these structures?

My drafts for this redesign can be found in pysal-base and in my copy of spreg. These are quite rough at present as development is ongoing. Descriptions of my development can be found on my blog.

Excited to hear your input!

Spatiol Temporal Prediction

Hey everyone, this is less of a feature request and more of a question. I hope this is the right place to ask this.

I am working on a project where I attempt to predict heroin overdose rates is the US by county using spreg, and I've run into 2 issues.

The first issue is that spreg models don't seem to have a predict function, so I can't actually predict with it. I'll be honest, I don't even know if the models in the spreg package are the right ones for this problem anyway.

The other problem I'm running into that I can't find a way to use both spatial and temporal components at the same time. If I arrange by data like this, I can't take calculate spatial weights since you can't do that with coincident points, which is what happens when you have multiple years of data for the same county

| County | Death Rate | Median Income | Year | geometry | |-------------|------------|---------------|------|--------------| | Alameda | 120 | 20000 | 2010 | Polygon(...) | | Alameda | 121 | 20100 | 2011 | Polygon(...) | | Los Angeles | 98 | 45000 | 2010 | Polygon(...) | | Los Angeles | 99 | 45100 | 2011 | Polygon(...) | | ... | ... | ... | ... | ... |

An example of a model I could use here that didn't take into account spatial effects is OLSRegimes.

If I do try to have spatial effects, then I can't have the data split by year, as I need to ensure the the same geometric point doesn't come up twice in the data, and the data has to look like this

| County | Death Rate 2010 | Median Income 2010 | Death Rate 2011 | Median Income 2011 | geometry | |-------------|-----------------|--------------------|-----------------|--------------------|--------------| | Alameda | 120 | 20000 | 121 | 20100 | Polygon(...) | | Los Angeles | 98 | 45000 | 99 | 45100 | Polygon(...) | | ... | ... | ... | ... | | ... |

And the models I've used so far like GM_Error_Het just haven't performed well so far.

Is there something I'm doing wrong here? Am I using the wrong models? Is something about my data not right? Or does pysal simply not support this functionality and I have to look elsewhere.

Fedora 33 with LLVM 11 and Python 3.9 breaks giddy and splot installation

The pysal metapackage fails in part to install on Fedora 33. The cause is that llvmlite, used by numba, quantecon, and then by giddy and splot, has not been extended to LLVM 11. Other Fedora components use LLVM 11, so multiple installs are not advisable. I have not been able to reconstruct the dependency graphs, so do not know whether the use of llvmlite is directly in giddy and splot, or via quantecon and numba, or numba seperately. It would be advisable to make at least some of the dependencies conditional. Note that I'm only using pip, and will never consider conda or similar mechanisms, so suggesting such a workaround isn't helpful.

v2.5.0(Aug 1, 2021)
PySAL 2.5.0 represents 6 months of enhancements, bug-fixes, widening of test coverage, and improved documentation. All users are encouraged to upgrade to this version as there are numerous optimizations as well as new features (see below) that have been implemented.

Overall, there were 543 commits that closed 190 issues, together with 33 pull requests since our last release on 2021-01-31.

Package Highlights

esda

This version merges two large new sets of functionalities:

map correspondence measures in esda.map_comparison

shape statistics in esda.shape

segregation

Version 2.0 of the segregation package brings a new API, a massive code restructuring, and dozens of new features, enhancements, and bug fixes. For a complete overview of the new API, please see the documentation page at https://pysal.org/segregation/api. The new version does away with the distinction between spatial and aspatial segregation indices and instead partitions the functions based on single-group and multi-group measures. The spatial/aspatial distinction is echewed in version 2.0 because all aspatial indices can be generalized into spatial versions, following the logic of Reardon and O'Sullivan (see a description in this example notebook). Furthermore, "space" can be incorporated into the index calculation using either Euclidean distance or the shortest path along a travel network. With this logic, the package now offers multiscalar segregation profiles for 23 different segregation indices (a first in any software package).

tobler

Added pychnophylactic interpolation.

spaghetti

The highlights of this release include functionality to split network arcs by count, which compliments the previously available distance splitting, and a paper in the Journal of Open Source Software. Also, Python 3.6 is no longer supported.

spopt

This release includes another model to add to the suite: RandomRegions. RandomRegions, originally written by David C. Folch (@dfolch) and Serge Rey, builds regions based on an initial random seed while considering user-defined specifications such as: region count, cardinality, contiguity, and compactness (citation?). Also, we have improved the testing coverage for the models inlcuded in the initial release: AZP, Max-p-regions, Region-k-means, Skater, Spenc, and WardSpatial.

v2.4.0(Feb 1, 2021)
PySAL 2.4.0 represents 6 months of enhancements, bug-fixes, widening of test coverage, and improved documentation. Three Google Summer of Code projects made substantial contributions to this release (see below). All users are encouraged to upgrade to this version as there are numerous optimizations as well as new features (see below) that have been implemented.

Overall, there were 1155 commits that closed 352 issues, together with 121 pull requests since our last release on 2020-07-29.

Highlights

New Package: pysal/spopt

Provides methods for solving optimization problems with spatial data. Currently, regionalization methods are supported with planned support for facility location and transportation-oriented modeling.

The regionalization models implemented include:

Max-p-regions: It involves the aggregation or clustering of a set of small areas into the maximum number of homogeneous and spatially contiguous regions such that the value of a regional attribute is higher than a predefined threshold. The number of regions will be endogenized in order to satisfy the threshold. (Duque, Anselin, and Rey, 2012 and Wei, Rey, and Knaap, 2020)

Automatic Zoning Procedure (AZP) algorithm: It can work with any type of objective function that is sensitive to the aggregation of data for a larger number of zones into a pre-specified smaller number of regions (Openshaw, 1977 and Openshaw and Rao, 1995)

Region-K-means: It is K-means clustering for regions with the constraint that each cluster forms a spatially connected component.

Skater: It is a constrained spatial regionalization algorithm based on spanning tree pruning. Specifically, the number of edges is prespecified to be cut in a continuous tree to group spatial units into contiguous regions. (AssunCao et al., 2006)

Spenc: spatially-encouraged spectral clustering is an approach to balance spatial and feature coherence using kernel combination in spectral clustering.([Wolf, 2020] (https://osf.io/yzt2p/))

WardSpatial: It is an Agglomerative Clustering using Ward linkage with a spatial connectivity constraint. Basically, it is a "bottom-up" approach: each observation starts in its own cluster, and pairs of clusters are chosen to merge at each step in order to minimize the variance of the clusters. (sklearn.cluster.AgglomerativeClustering)

Enhancements to existing packages

libpysal

Thanks to the Google Summer of Code 2020 led by Mragank Shekhar (@MgeeeeK), we have built an interface with xarray that allows you to create spatial weights matrices from xarray.DataArray objects. This means it is possible to build a weights matrix from raster data. We are using numba and multi-core where possible so the implementation is performant and scalable within memory limits. Current weights supported include:

libpysal.weights.Rook.from_xarray

libpysal.weights.Queen.from_xarray

In addition, the following methods have been added and are exposed to end users:

[RECOMMENDED] da2WSP, to build a thin weights matrix (WSP) from a xarray.DataArray da2W, to build a weights matrix from a xarray.DataArray

[RECOMMENDED] wsp2da, to reconstruct a xarray.DataArray object from a thin weights matrix and a pandas.Series (e.g. with mapclassify or esda.Moran_Local outcomes

w2da, to reconstruct a xarray.DataArray object from a weights matrix and a pandas.Series (e.g. with mapclassify or esda.Moran_Local outcomes testDataArray, to generate a toy xarray.DataArray object for testing purposes.

esda

Integration of the work of @jeffcsauer's 2020 GSOC project. This adds tons of new statistical estimators, such as:

the local heteroskedasticity estimator, esda.LOSH

local geary and multivariate geary estimators, esda.Geary_Local and esda.Geary_Local_MV

local join counts in univariate, bivariate, and multivariate flavors, esda.Join_Counts_Local, esda.Join_Counts_Local_BV, and esda.Join_Counts_Local_MV.

"analytical" moments for Moran's I for replication/comparison to R. Forms are provided in Sokal 1998.

spreg

Thanks to the Google Summer of Code 2020 led by paboloestrada, we have added the following functionality:

Panel_RE_Lag: random effects panel estimation with spatial lagged dependent variable.

Panel_RE_Error: random effects panel estimation with spatial error interaction.

Lagrange Multiplier test: classic and robust version.

Hausman test.

spaghetti

The highlights of this release include a bug fix for how network segments were being split (raised in #526) and additions to several notebooks (spatial network segmentation, caveats, and network-constrained spatial autocorrelation). Also, spaghetti is now tested against Python 3.9.

esda

Integration of the work of @jeffcsauer's 2020 GSOC project. This adds tons of new statistical estimators, such as:

the local heteroskedasticity estimator, esda.LOSH

local geary and multivariate geary estimators, esda.Geary_Local and esda.Geary_Local_MV

local join counts in univariate, bivariate, and multivariate flavors, esda.Join_Counts_Local, esda.Join_Counts_Local_BV, and esda.Join_Counts_Local_MV.

"analytical" moments for Moran's I for replication/comparison to R. Forms are provided in Sokal 1998.

v2.3.0(Jul 30, 2020)
PySAL 2.3.0 represents 6 months of enhancements, bug-fixes, widening of test coverage, and improved documentation. All users are encouraged to upgrade to this version as there are numerous optimizations as well as new features (see below) that have been implemented.

Overall, there were 1343 commits that closed 273 issues, together with 166 pull requests since our last release on 2020-02-09.

Major Highlights of PySAL 2.3.0

Entirely New Packages

In this release, the PySAL family has expanded to include:

pysal/access

Providing classical and novel measures of spatial accessibility to services.

We implement classic spatial access models, allowing easy comparison of methodologies and assumptions.

We support spatial access research by providing pre-computed travel time matrices and share code for computing new matrices at scale.

We also developed a simple web app that runs the package on Amazon Web Services, allowing users to explore results without installing the package. We think this is a fun new strategy for trying new analysis methods, and hope that it will make the package more accessible to professionals.

This access models implemented include:

Floating Catchment Areas (FCA): For each provider, this is the ratio of providers to clients within a given travel time to the provider (Huff 1963, Joseph and Bantock 1982, and Luo 2004).

Two-Stage FCAs (2SFCA): Calculated in two steps for a given travel time to the provider: 1) for each provider, the provider-to-client ratio is generated, 2) for each point of origin, these ratios are then summed (Luo and Wang 2002, and Wang and Luo 2005).

Enhanced 2SFCA (E2SFCA): 2SFCA but with less weight to providers that are still within the travel threshold but at larger distances from the point of origin (Luo and Qi 2009).

Three-Stage FCA (3SFCA): adds distance-based allocation function to E2SFCA (Wan, Zou, and Sternberg, 2012).

Rational Agent Access Model (RAAM) (Saxon and Snow 2019).

Access Score: This is a weighted sum of access components like distance to provider and relative importance of provider type (Isard 1960).

The package is implemented as a single class with a number of helper functions. According to PySAL tradition, we have also developed a broad set of tutorials and examples.

Enhancements to Existing Packages

pysal/esda

Highly performant multi-core, numba-based conditional permutation inference for local autocorrelation statistics (#116)

Adbscan: an extension of the original DBSCAN algorithm that creates an ensemble of solutions generated by running DBSCAN on a random subset and "extending" the solution to the rest of the sample through nearest-neighbor regression (see Arribas-Bel, Garcia-Lopez & Viladecans-Marsal, 2020 for more details). (#120)

pysal/spaghetti

Improved support for native PySAL geometry objects

Longest and largest network component identification

Minimum/maximum spanning trees

Network component extraction

Refactored K function

Regular lattice generator

Shortest path creation and extraction

Testing improvements — Python 3.6, 3.7, 3.8 on Linux, macOS, and Windows

Tutorial improvements and additions

pysal/mapclassify

Toplogical coloring to ensure no two adjacent polygons share the same color.

Pooled classification allows for the use of the same class intervals across maps.

pysal/spreg

New documentation website.

pysal/libpysal

pysal/giddy

Testing improvements: GitHub Actions for Continuous Integration — Python 3.6, 3.7, 3.8 on Linux, macOS, and Windows

pysal/splot

splot 1.1.3 was published as Lumnitz et al., (2020). splot - visual analytics for spatial statistics. Journal of Open Source Software, 5(47), 1882, https://doi.org/10.21105/joss.01882 featuring functionality, implementation and it's roadmap forward.

v2.2.0(Feb 13, 2020)

PySAL v<2.2.0>, 2020-02-13

PySAL 2.2.0 represents 6 months of enhancements, bug-fixes, widening of test coverage, and improved documentation. All users are encouraged to upgrade to this version as there are numerous optimizations as well as new features (see below) that have been implemented.

Overall, there were 1122 commits that closed 307 issues, together with 192 pull requests since our last release on 2019-07-29.

Major Highlights of PySAL 2.2.0

Meta-package loses some serious weight

PySAL is no longer a source release meta-package, but instead specifies the packages in the PySAL ecosystem as dependencies. This means that installing the pysal meta-package will ensure that all the ecosystem packages are installed.

Entirely New Packages

In this release, the PySAL family has expanded to include:

tobler Areal interpolation and dasymetric mapping.

Enhancements to Existing Packages

Refactoring of pysal/libpysal to use remote example data sets which reduces the footprint of the source install from 25mb to under 3mb. Remote examples can now be examined with interactive maps if being run in Jupyter Notebooks.
pysal/mapclassify: Choropleth legend formatting has been enhanced to permit more granular control of class labels.
pysal/spaghetti: This release includes a major overhaul to the API documentation and notebooks/tutorials.
pysal/splot: This release includes additional documentation, in-depth tutorials and pointers how to solve common installation issues. splot has been submitted and will soon be available as an article in the journal of open source software.
pysal/giddy: Two enhancements: (1) a new sequence module consisting of several alignment-based sequence analysis methods (example notebook) (2) extend Markov methods to deal with non-ergodic Markov chains. This release also includes a bug fix for the estimation of kendall's Tau and its spatial extension when ties are present.

v2.1.0(Jul 29, 2019)

PySAL 2.1.0 represents 6 months of enhancements, bug-fixes, widening of test coverage, and improved documentation. All users are encouraged to upgrade to this version as there are numerous optimizations as well as new features (see below) that have been implemented.

From this version forward, PySAL supports Python 3 only and is tested on Python 3.6 and 3.7. Please make sure that you are operating in a Python 3 environment.

Major Highlights of PySAL 2.1.0

Entirely New Packages

This release we have added the following new package(s) to the PySAL stack:

segregation. Segregation Analytics with PySAL.

This is an extensive package that deals with segregation measurements with several frameworks ranging from inference, decomposition, street network based measures, and a multiscalar segregation profiles on urban street networks. With a consistent and well defined api following the pep8 standards, users of segregation (v1.1.1) can:

Calculate over 40 segregation measures from simple to state-of-the art, including:

Test whether segregation estimates are statistically significant:

Decompose segregation comparisons into

differences arising from spatial structure
differences arising from demographic structure

Significant Enhancements to Existing Packages

Addition of two rank-based Markov methods to pysal/giddy: Full Rank Markov and Geographic Rank Markov, both of which avoid the potentially arbitrary selection of the discretization scheme when a discrete Markov chain is applied to continuous variables (e.g. incomes). An example notebook applying these two methods to reveal interesting spatiotemporal patterns of income distribution dynamics in the United States 1929-2009 is given here.
A new function fdr in pysal/esda which account for multiple testing in local statistics by controlling the False Discovery Rate (FDR). The function takes the p-values for all of n local statistics and the significance level as the inputs, and returns the p-value cutoff which would be used for deciding whether to reject the null for each local test.
The S-MAUP test was added to esda. This test statistic measures the sensitivity of statistical results to re-aggregation. Contributed by Juan Carlos Duque (@JuancaDuque), the statistic is defined in this PLOS paper.
The Lee & Local Lee statistics were added to esda. These statistics characterize the structure of local autocorrelation using Pearson's r. The statistic is defined in Lee (2001).
The notebooks project, which provides a centralised online site with example notebooks from all the federated packages has undergone several back-end improvements and (partially) supports now interactive notebooks through Binder. The project is available at http://pysal.org/notebooks
Computational improvements to mgwr package includes memory optimization and parallelization. The update allows GWR and Multi-scale GWR model to be calibrated faster and on much larger datasets. Additionally, there are API changes to the kernel functions in mgwr. (#55)

Changes by Package

Overall, there were 992 commits that closed 261 issues, together with 173 pull requests since our last release on 2019-01-30.

Release Notes for PySAL 2.0

Major Changes

This release, we've had a ton of activity in PySAL, much of which has been conducted in our subpackages, the independently-released components of our library. Because it is too onerous to list all the changes to the API here, please consult the Migrating to PySAL 2.0 page for a detailed discussion of all reorganization-related changes. This document will focus only on improvements to functionality, enhancements, and additional modules added to 2.0, over and above the last stable release of the 1.0 series, PySAL 1.14.4.

Entirely New Packages

For starters, we've added some entirely-new subpackages to this release candidate:

mgwr, the multi-scale Geographically-weighted regression package for Python.

Don't worry, mgwr fits single-scale geographically-weighted regressions, too. Geographically-weighted regression is a kind of generalized additive model that uses kernel functions in the geographic area around each observation to predict outcomes at that area more accuratly, kind of like Gaussian Process regression for geographic data.
spvcm, for spatially-correlated multilevel models.

Spatially-correlated multilevel models are models that allow for random effects of nearby areas, regions, or groups to be correlated with one another. This is a Gibbs sampling framework plus diagnostics & plotting tools for general Bayesian analysis of Gibbs samplers. The package also contains simple tools to implement new samplers on top of the infrastructure provided, which is fast, parallel, serializable, iterative-write, and interruptible.
spint, for estimating spatial interaction models, such as the production-constrained or consumption-constrained gravity models.
spglm, a package for fitting sparse GLMs, focused on performance over sparse categorical data.
splot, for spatial vizualization in Python, built on top of the excellent geopandas. This is headed by our Google Summer of Code (2018) student, Stefanie Lumnitz, and will be ongoing throughout the release candidate maturation cycle.
pointpats, a package for the statistical analysis of point patterns, geographical colocation, and dispersion.

Significant Enhancements to Existing Packages

We've also had a ton of activity adding new features in our submodules:

alpha shapes, a fast implementation (numba-enabled) of the original algorithm generalizing convex hulls to allow for non-convex hulls
Contiguity weights from voronoi tesselations/delaunay triangulation graphs for point patterns
Fuzzy contiguity weights, for polygonal data where planarity is not strictly enforced (provided in part by geopandas)
A family of spatially explicit indicators of mobility association including the inter- and intra-regional indicators as well as the local indicators. The inter- and intra-regional indicators provide a meso-level view on the exchange mobility pattern, shedding light on specific regions hosting frequent rank exchanges while the local indicators examine the concordance relationship between a focal spatial unit and its neighbors for revealing the role of space in shaping the exchange mobility pattern over time.
Categorical Spatial Markov, a generalization of the Spatial_Markov class previously implemented to interrogate the role of space in shaping regional income distribution dynamics to incorporate direct variables. Here, the categorical spatial lag is adopted for formalizing the neighborhood.
Connected Components checks for our spatial graph matrices
Pandas Adjacency list constructors and NetworkX adapters for PySAL graph objects
Attach islands, tooling to merge isolated observations into existing spatial graphs
Construct Contiguity graphs from linestrings, allowing for easy and fast access to road network data in PySAL

2.0rc2(Jul 20, 2018)

Release Notes for PySAL`2.0rc2`

For starters, these change notes are only for this release candidate, which is like a typical release of PySAL, but considered a preview. This release candidate, 2.0rc2, signifies that our API will change (the 2.0 part) and that we want to ensure users can opt-in to these changes with a longer time delay than a usual release (the rc2 part). We will make a full release of PySAL 2.0 by 2018-12-31, which will largely follow the API reorganization in this release candidate (and any subsequent release candidates). For more information on how to migrate to the 2.0-API, please check out migrating.pysal.org.

Feature Changes in `2.0rc2`

This release, we've had a ton of activity in PySAL, but it has all been conducted in our subpackages, the independently-released components of our library. Because it is too onerous to list all the changes to the API here, please consult the migrating.pysal.org website for a detailed discussion of all reorganization-related changes. This document will focus only on improvements to functionality, enhancements, and additional modules added to 2.0rc2, over and above the last stable release of the 1.0 series, PySAL 1.14.4.

Overall, there were 719 commits that closed 240 issues, together with 105 pull requests across 12 packages since our last release on 2017-11-03.

Entirely New Packages

For starters, we've added some entirely-new subpackages to this release candidate:

mgwr, the multi-scale Geographically-weighted regression package for Python.

Don't worry, mgwr fits single-scale geographically-weighted regressions, too. Geographically-weighted regression is a kind of generalized additive model that uses kernel functions in the geographic area around each observation to predict outcomes at that area more accuratly, kind of like Gaussian Process regression for geographic data.
spvcm, for spatially-correlated multilevel models.

Spatially-correlated multilevel models are models that allow for random effects of nearby areas, regions, or groups to be correlated with one another. This is a Gibbs sampling framework plus diagnostics & plotting tools for general Bayesian analysis of Gibbs samplers. The package also contains simple tools to implement new samplers on top of the infrastructure provided, which is fast, parallel, serializable, iterative-write, and interruptible.
spint, for estimating spatial interaction models, such as the production-constrained or consumption-constrained gravity models.
spglm, a package for fitting sparse GLMs, focused on performance over sparse categorical data.
splot, for spatial vizualization in Python, built on top of the excellent geopandas. This is headed by our Google Summer of Code (2018) student, Stefanie Lumnitz, and will be ongoing throughout the release candidate maturation cycle.
pointpats, a package for the statistical analysis of point patterns, geographical colocation, and dispersion.

Significant Enhancements to Existing Packages

We've also had a ton of activity adding new features in our submodules:

alpha shapes, a generalization of convex hulls to allow for non-convex hulls
Contiguity weights from voronoi tesselations/delaunay triangulation graphs for point patterns
Fuzzy contiguity weights, for polygonal data where planarity is not strictly enforced (provided in part by geopandas)
A family of spatially explicit indicators of mobility association including the inter- and intra-regional indicators as well as the local indicators. The former provide a meso-level view on the exchange mobility pattern, shedding light on specific regions hosting frequent rank exchanges while the latter examine the concordance relationship between a focal spatial unit and its neighbors for revealing the role of space in shaping the exchange mobility pattern over time.
Categorical Spatial Markov, a generalization of the Spatial_Markov class previously implemented to interrogate the role of space in shaping regional income distribution dynamics to incorporate directe variables. Here, the categorical spatial lag is adopted for formalizing the neighborhood.
Connected Components checks for our spatial graph matrices
Pandas Adjacency list constructors and NetworkX adapters for PySAL graph objects
Attach islands, tooling to merge isolated observations into existing spatial graphs
Construct Contiguity graphs from linestrings, allowing for easy and fast access to road network data in PySAL
