pauloxnet – Maps with Django (part 2): GeoDjango, PostGIS and Leaflet

A quickstart guide to create a web map with the Python-based web framework Django using its module GeoDjango, the PostgreSQL database with its spatial extension PostGIS and Leaflet, a JavaScript library for interactive maps.

Keeping in mind the Pythonic principle that “simple is better than complex” we’ll see how to create a web map with the Python based web framework Django using its GeoDjango module, storing geographic data in your PostgreSQL database on which to run geospatial queries with PostGIS.

A map in a website is the best way to make geographic data easily accessible to users because it represents, in a simple way, the information relating to a specific geographical area and is in fact used by many online services.

Implementing a web map can be complex and many adopt the strategy of using external services, but in most cases this strategy turns out to be a major data and cost management problem.
