Cropping (sometimes also referred to as clipping), is when you subset or make a dataset smaller, by removing all data outside of the crop area or spatial extent. Both examples work well, but they are terribly inefficient and won't process a really big raster. It lets you read the common vector and raster geospatial formats (leveraging on well known libraries such as fiona, shapely and rasterio) and makes it extremely easy to combine data sources with different projections, visualize them, read and write them from/to. merge(datasets, bounds = *polygon. filterwarnings ("ignore").
