A concise guide for full stack developers to harness geospatial queries for location-based features—proximity search, routing, and AR—covering core query types (point-in-polygon, distance, buffers, spatial joins), challenges (scalability, performance, data quality), tools (PostGIS, GeoJSON, Elasticsearch, Firestore/Geofirestore), best practices (indexes, formats, caching, monitoring), plus a food-delivery example.
Fullstack.ist offers meaningful insight into a broad range of topics.
