You can perform some of the Shapely operations after importing Geopandas without a separate import, however, if you want to work directly with Point and Polygon objects — you would still …
WebbThen from this shortlist list, you'd go through them and use Shapely to determine which polygon is closest, based on the minimum distance between the geometries. Find and exclude polygons using GeoPandas. WebbKNN (also stylized as kNN) is a neighbor-based learning method that can be used for interpolation. Unlike the Thiessen polygons method, KNN looks for a specified number K of sampled points closest to an unknown point. The K known points can be used to predict the value (discrete or continuous) of the unknown point. 3.
