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.
