Title: PostGIS – geographical search
Links: slides

Postgis is an extension for the postgres database to handle geographical data. This is not actually as complicated to use as it sounds - it gives you support for coordinates as column type, and allows to query for areas. I will explain the basics and show some examples how we use this in the Swiss Buildings API project.
