PostGIS

PostGIS is an extension for the PostgreSQL database that adds support for geographic objects, allowing users to store and query spatial data efficiently. It enables advanced geographic information system (GIS) functionalities, such as mapping, measuring distances, and performing spatial analysis. This means developers can work with data that has location-based attributes, like addresses or geographical coordinates, making it easier to create applications that involve maps, urban planning, or environmental studies. Essentially, PostGIS turns a standard database into a powerful tool for handling geographical information.
