Setup custom projection system

If you want to work with a specific projection system (typically a national projetion system) and a specific region (typically a nation), you must first define the projection system, then the geographical region and finally a user with a project that use the defined region. This blog covers how to add the required schemas and tables to the PostgreSQL database and then add the required process links for the new projection system. The blog uses the Swedish national projection system, SWEREF99 (EPSG: 3006), as an example.
