Webb17 mars 2024 · I am new to Shapely (but enthusiastic about it), and recently I've discovered a bit of a road bump. I have a polygon shapefile that I am reading in via Fiona. This shapefile contains BOTH polygon and multipolygon items and I need to build an array for each feature of all the coordinates within it (i.e. both exterior and/or interior). Webbshapely is a Python package for working with vector geometries, that is, the geometric component of vector layers (the other component being non-spatial attributes). shapely includes functions for creating geometries, as well as functions for applying geometric operations on geometries, such as calculating the centroid of a polygon.
