PostGIS extends the capabilities of the PostgreSQL relational database by adding support for storing, indexing, and querying geospatial data.

PostGIS features include:

  • Spatial Data Storage: Store different types of spatial data such as points, lines, polygons, and multi-geometries, in both 2D and 3D data.
  • 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.
