# 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 |
