dask-rasterio provides some methods for reading and writing rasters in parallel using Rasterio and Dask arrays.

Usage

Read a multiband raster

>>> from dask_rasterio import read_raster

>>> array = read_raster('tests/data/RGB.byte.tif')
>>> array
dask.array<stack, shape=(3, 718, 791), dtype=uint8, chunksize=(1, 3, 791)>

>>> array.mean()
dask.array<mean_agg-aggregate, shape=(), dtype=float64, chunksize=()>
>>> array.mean().compute()
40.858976977533935

Read a single band from a raster

>>> from dask_rasterio import read_raster

>>> array = read_raster('tests/data/RGB.byte.tif', band=3)
>>> array
dask.array<raster, shape=(718, 791), dtype=uint8, chunksize=(3, 791)>

Write a singleband or multiband raster

>>> from dask_rasterio import read_raster, write_raster

>>> array = read_raster('tests/data/RGB.byte.tif')

>>> new_array = array & (array > 100)
>>> new_array
dask.array<and_, shape=(3, 718, 791), dtype=uint8, chunksize=(1, 3, 791)>

>>> prof = ... # reuse profile from tests/data/RGB.byte.tif...
>>> write_raster('processed_image.tif', new_array, **prof)

Chunk size

Both read_raster and write_raster accept a block_size argument that acts as a multiplier to the block size of rasters. The default value is 1, which means the dask array chunk size will be the same as the block size of the raster file. You will have to adjust this value depending on the specification of your machine (how much memory do you have, and the block size of the raster).

Install

Install with pip:

pip install dask-rasterio

Development

This project is managed by Poetry. If you do not have it installed, please refer to Poetry instructions.

Now, clone the repository and run poetry install. This will create a virtual environment and install all required packages there.

Run poetry run pytest to run all tests.

Run poetry build to build package on dist/.

    the time to write a dask array in tif is too long?

    I have a image which have 40000cols and 40000 rows ,while I use data = read_raster(filename, band=1), and the use witer_raster(out_filename, data), it need about one minutes, I want to know can it be quickly

  • Does dask-rasterio support masked array?

    Does dask-rasterio support masked array?

    I'm working with dask masked array, and was wondering what would be the translation of these lines?

        import rasterio
    with rasterio.open(inputFile) as source:
        # this is a 3D numpy array, with dimensions [band, row, col]
        src_array = source.read(masked=True)

    Thank you for your cool lib!
