location

Geospatial data represents geographic locations and shapes. I use PostGIS for spatial queries. Point data stores coordinates—latitude, longitude. LineString represents paths. Polygon defines areas. Spatial indexes (GIST) enable fast proximity queries.

MapKit displays interactive maps with annotations, overlays, and user location. SwiftUI's Map view simplifies basic map integration with declarative syntax. I add annotations for points of interest, polylines for routes, and polygons for regions. MKCo
