Any groupby operation involves one of the following operations on the original object. If you’re cycling in the Netherlands, especially in hilly areas, you may well find yourself on a road named Holleweg (Holloway). Below, I go through an example where I read in the points layer from the OSM data using the OGR driver, extract relevant attributes and location, convert the data to a GeoPandas GeoDataFrame, and then plot it on a map. A GeoSeries is made up of an index and a GeoPandas geometry data type. This is the first of a four-part exploratory data analysis project on an open source parking citation dataset. import geopandas as gpd import pandas as pd from shapely. mask module but I don't know what format the input data needs to be. pandas has an abundance of functionality, far too much for me to cover in this introduction.
