Use ST_Intersection to extract values from satellite imagery based on vector boundaries (e.g., calculating average rainfall per county). 🚀 Performance Optimization
Use ST_Subdivide on large, complex polygons to significantly boost intersection performance. Mastering PostGIS: Modern ways to create, analy...
Use ST_ClusterKMeans to group massive datasets into spatial clusters without leaving SQL. Use ST_Intersection to extract values from satellite imagery
For massive, chronologically sorted datasets (like GPS pings), BRIN indexes are much smaller and faster than traditional GiST indexes. chronologically sorted datasets (like GPS pings)
Run ST_IsValid and ST_MakeValid to clean "dirty" geometry on the fly.
Link external files (GeoJSON, Shapefiles, CSVs) as virtual tables without importing data.
Generate Mapbox Vector Tiles directly in the database for lightning-fast web mapping.
