The combined places shapefile that we created with geopandas: cbf_places_2015_500k; Covering PostGIS and CartoDB is a topic too broad for this tutorial, but I’ve written a separate one for the Stanford Journalism curriculum that you can follow: Using PostGIS, SQL, and CartoDB to identify schools at risk from Oklahoma’s earthquakes. so here's the. GeoPandas extends the datatypes used by pandas to allow spatial operations on geometric types. Today, using an accelerated GeoPandas and a new dask-geopandas library, we can do the above computation in around eight minutes (half of which is reading CSV files) and so can produce a number of other interesting images with faster interaction times. Learn how to dissolve (aggregate) polygons into larger units, and apply spatial joins across GeoDataFrames, as examples of GeoPandas spatial operators.
