In this lesson, we will get to know how geopandas handles some typical GIS operations: overlay analysis (e.g., unions, or differences of multiple geometries), aggregating geometries (e.g., smaller statistical units into larger ones), simplifying geometries (to be printed or shown at smaller map scales), and classifying numerical data into categories for map display.
After this lesson, you should know how to:
create new geometries by adding, subtracting or intersecting two geometries,
combine geometries based on a common attribute (dissolving them),
create categories for numerical data based on classifiers such as natural breaks, equal interval, or quantiles, and
simplify geometries according to a maximum-error threshold
