Geospatial Analysis with GeoPandas
Overview
When working with geographic data (earthquakes, plate boundaries, etc.), using geopandas with proper coordinate projections provides accurate distance calculations and efficient spatial operations. This guide covers best practices for geospatial analysis.
Key Concepts
Geographic vs Projected Coordinate Systems
| Coordinate System | Type | Units | Use Case |
|---|---|---|---|
| EPSG:4326 (WGS84) | Geographic | Degrees (lat/lon) | Data storage, display |
| EPSG:4087 (World Equidistant Cylindrical) | Projected | Meters | Distance calculations |
Critical Rule: Never calculate distances directly in geographic coordinates (EPSG:4326). Always project to a metric coordinate system first.
