This won'y work for really large datasets. I get a MemoryError Source raster (geo units): Origin (top left): 2519950.0001220703, 5520150.00012207 Pixel size (x,-y): 100.0, -100.0 Columns, rows : 42000, 43200 Traceback (most recent call last): File "D:/11202067_COACCH/local_checkout/crop_raster.py", line 72, in <module> cropped_raster, cropped_transform = main(src_raster) File "D:/11202067_COACCH/local_checkout/crop_raster.py", line 22, in main data = np.array(raster.ReadAsArray()) MemoryError
