PostGIS/GeoDjango Installation

This tutorial will guide you through the installation of PostGIS, an extension for Postgres that enables it to store Geographic data directly in the database.

On MacOS

1. Install Postgres and Geo Libraries

brew install postgis
brew install gdal
brew install libgeoip
brew install libmemcached

2. Create PostGis Extension

Run these lines in the terminal. Note: you must have created your Postgres database in the previous tutorial for this to work!

psql representable_db
CREATE EXTENSION postgis;

On Linux

caution

The postgis libraries referenced here are out of date and should be updated to Postgres12.
