This is an experiment in building map backends over a weekend

What's to implement

  • Tiles
  • Geocoding
  • Reverse geocoding
  • Free-form geocoding
  • Place tagging (through JS libs)
  • Routing for bikes and pedestrian
  • Routing for cars
  • Staticmaps

How to start

All of these have to use OpenStreetMap data. Links for getting OSM data (huge amounts):

How to load data into PostGIS (or any other data storage of your liking): http://wiki.openstreetmap.org/wiki/Planet.osm#Technical_notes

Common building blocks:

Mapnik
Rendering library
Nominatim
Structured geocoding framework
Open Source Routing Machine
Good example of Contraction Hierarchies algorithm implementation. Unfortunately, license is as bad as it can be (AGPL).
