QGIS and TileMill

Once you are done setting up your Benefice database, you can use the following tools (including psql) to explore the datasets.

QGIS is a free, open-source GIS application that can connect directly to a PostGIS database and display and analyze geographic data.

TileMill is a map-design studio that can also connect directly to a PostGIS datastore and create interactive web maps using OpenStreetMap as the base layer.
