GeoWombat is a Python package for geo-utilities applied to air- and space-borne imagery

Like a wombat, GeoWombat has a simple interface with a strong backend. GeoWombat uses Rasterio, Xarray and Dask for I/O and distributed computing with named coordinates.

Basic usage

>>> import geowombat as gw
>>>
>>> # Open images as Xarray DataArrays
>>> with gw.open('image.tif', chunks=512) as ds:
>>>
>>>     # Do Xarray and Dask operations
>>>     dss = ds * 10.0
>>>
>>>     # Write the computation task to file using 16 parallel jobs
>>>     dss.gw.to_raster('output.tif', n_workers=4, n_threads=4)
