GeoPandas - Geospatial Data Analysis
GeoPandas enables you to perform spatial joins, geometric manipulations, and coordinate transformations using the familiar Pandas API. It treats "geometry" as just another column in a DataFrame, but one that knows how to calculate areas, distances, and intersections.
When to Use
- Reading and writing spatial formats (Shapefile, GeoJSON, GeoPackage, KML).
- Performing spatial joins (e.g., "which points fall inside this polygon?").
- Coordinating system transformations (reprojecting from Lat/Lon to Meters).
- Geometric analysis (calculating buffers, centroids, convex hulls).
- Thematic mapping (Choropleth maps).
- Calculating spatial relationships (contains, overlaps, touches, within).
- Working with OpenStreetMap data or satellite-derived vector data.
