This is part one of a five-part series about our recent explorations making choropleth maps using PostGIS, TileMill, Mapnik and Google Maps.
Turns out to be total of six posts, but it’s still a handy, not too deep, dive into making maps. Forewarned, there’s a fair bit of command line tweakage and assumed familiarity with open source tech. (Python Inside!) Not for those used to a lot of desktop app handholding.
