Another reason to use Numpy is tight integration with GDAL in the form of the "GDALNumeric" module. Is there a way to sum N rasters of different shape using rasterio (the rasters have different bounding boxes, there can be an area that overlaps or they don't need to overlaps) The objective is to get the result of the operation and write it to the file, limiting the output raster to the area of "common bbox". 0000000000. They are extracted from open source Python projects. Take some point from polygon as an example: We will use function rasterio. GDAL¶ GDAL is a translator library for raster and vector geospatial data formats that is released under an X/MIT style Open Source License by the Open Source Geospatial Foundation. I've noticed a limitation in gdal_rasterize: it seems to be saving all values as 8-bit data regardless of the data type of the target image. But of course you can always get the numpy array and affine transformation matrix from a raster on disk using rasterio. The only downside: rasterize_geom is ~ 1.
