Shapely centroid of linestring
WebbHow to use shapely - 10 common examples To help you get started, we’ve selected a few shapely examples, based on popular ways it is used in public projects. WebbA line (in Shapely called LineString) instance can be created in two ways. We can chose to first define the connected points that make up the line and use these objects to define the line geometry. Alternatively we can define the line in one go by providing the coordinates of each point in a list form.
