These operations will allow you to quickly logically separate data based on conditions or attributes from a set or collections of datasets.

For this you need python (version 3.8<) as well as the following packages imported: matplotlib.pyplot and geopandas.

The example shows you how to:

• Set a collection of values belonging to groups.

• Return a list of the sets based specific operations (Union, intersection, difference, and symmetric difference)

• Apply these set operations in a spatial context.

Set operations are very useful in geospatial analysis and having confidence using them will save both time and googling!
