Finally, the parameter “predicate” tells GeoPandas which geopandas. sindex. There are three different join options as follows: intersects: The attributes will be joined if the boundary and interior of the object intersect in any way with the boundary and/or interior of the other object. Indexing and selecting data#. The op argument specifies how geopandas decides whether or not to join the attributes of one object to another. Alternatively, you can filter polygons which contain points. Knowing how to perform a spatial join is an important asset in your data-processing toolkit: it enables you to join two datasets based on spatial predicates. The user guide covers different parts of basic usage of GeoPandas.
