What Is PostGIS? PostGIS is an open source, freely available, and fairly OGC compliant spatial database extender for the PostgreSQL Database Management System. In a nutshell it adds spatial functions such as distance, area, union, intersection, and specialty geometry data types to the database. Spatial aggregate functions are much like regular SQL aggregate functions such as AVG, SUM, COUNT in that they work with GROUP BY and HAVING predicates and collapse multiple records into a single record.

2021-04-17 · Looking at the installed PostGIS functions¶ PostGIS can be thought of as a collection of in-database functions that extend the core capabilities of PostgreSQL so that it can deal with spatial data. By ‘deal with’, we mean store, retrieve, query and manipulate. In order to do this, a number of functions are installed into the database.
