geopandas

Python library for working with geospatial vector data including Shapefiles, GeoJSON, and GeoPackage files. Use it when handling geographic data for spatial analysis, geometric operations, coordinate transformations, spatial joins, overlay operations, choropleth mapping, or any task involving reading, writing, or analyzing vector geographic data. Supports PostGIS databases, interactive maps, and integration with matplotlib, folium, cartopy, and contextily. Useful for tasks like buffer analysis, spatial joins between datasets, dissolving boundaries, clipping data, calculating areas and distances, reprojecting coordinate systems, creating maps, or converting between spatial file formats.
