# Postgis

[Postgis](https://postgis.net/) is a spatial database extender for PostgreSQL object-relational database. It adds support for geographic objects allowing location queries to be run in SQL. 

Services like [Mobilizon](./mobilizon.md) depend on the ability to store gespatial data. 
Enabling the PPostgisostgres database service will automatically wire these services to use it.


## Configuration

To enable this service, add the following configuration to your `vars.yml` file and re-run the [installation](../installing.md) process:
