WebbWhen comparing Shapely and geojson you can also consider the following projects: geopy - Geocoding library for Python. Here’s an example of an input GeoJSON (as a Python dictionary) to be fed to the final split_polygon function (see bottom of. For this example we'll use The Nature Conservancy's Terrestrial Ecoregions spatial data layer.

WebbA Polygon is allowed to have self-intersections, this is conform with the GeoJSON specification. However, it frequently causes issues in downstream applications thus is often rejected by APIs and tools. A common approach for removing the self-intersections is applying a zero-buffer operation (e.g. .buffer(0) in shapely).
