Shapely from wkb
WebbGeometric objects in any Python package (e.g. GDAL, shapely) are usually based on the geometries that can be represented in WKT strings. As such, it is useful to know how to write geometries in WKT; then you do not need to learn the specific way of each individual Python package.
