- `offset_coordinates`: Move a WGS84 point by a geodesic distance and bearing
- `overlay_geojson`: Boolean set operation (intersection/difference/symmetric_difference/union) between two GeoJSON inputs
- `reduce_precision`: Round GeoJSON coordinates to N decimal places (shrinks payload size)
- `reproject_geojson`: Reproject an entire GeoJSON between EPSG coordinate systems
