GeoPandas is your go-to for working with shapefiles, GeoJSON, and other vector geographic data in Python. It extends pandas with spatial operations, so you can do buffer analysis, spatial joins, coordinate transformations, and overlay operations without leaving the dataframe paradigm. The skill covers everything from basic read/write operations to complex workflows like multi-source integration and PostGIS connections. One thing worth noting: it emphasizes using projected coordinate systems for area and distance calculations, which trips up a lot of people new to GIS work. The performance tips about Arrow acceleration for I/O and spatial indexing are genuinely useful if you're dealing with large datasets.
