PostGIS is an open source software extension for PostgreSQL that adds support for advanced spatial data types and functions, allowing users to store, manipulate, and analyze geographic and geometric data in a relational database. It supports a wide range of geometry and geography types, including points, lines, polygons, and multi-geometries, and provides a powerful set of spatial functions for spatial analysis, such as distance calculations, buffer operations, and spatial joins. With PostGIS, users can build complex spatial applications and perform sophisticated spatial analysis, all within the familiar environment of a relational database management system.
