  • Spatial Indexing: Quickly search and retrieve spatial data based on its location.
  • Spatial Functions: A wide range of spatial functions that allow you to filter and analyze spatial data, measuring distances and areas, intersecting geometries, buffering, and more.
  • Geometry Processing: Tools for processing and manipulating geometry data, such as simplification, conversion, and generalization.
  • Raster Data Support: Storage and processing of raster data, such as elevation data and weather data.
  • Geocoding and Reverse Geocoding: Functions for geocoding and reverse geocoding.
  • Integration: Access and work with PostGIS using third party tools such as QGIS, GeoServer, MapServer, ArcGIS, Tableau.

PostGIS Tiger Geocoder 2025.1

The PostGIS development team is pleased to provide postgis_tiger_geocoder extension. This is the very first release since the break from the PostGIS core. This version requires PostgreSQL 16 and above and should work with any supported PostGIS version.

PostGIS 3.6 series is the last series to include postgis_tiger_geocoder. PostGIS 3.7 will be shipped without postgis_tiger_geocoder.

Moving forward postgis_tiger_geocoder has its own dedicated repo at OSGeo Gitea postgis_tiger_geocoder under the PostGIS org.
