Ever wondered how web maps are created? Ever wondered if you
could build something like Google Maps over a weekend? You
probably can't, but this talk will show you the basics of
what you need to know, such as importing data, rendering
maps and even building simple routes. And all of this in
* Learning how OSM data looks
* Parsing and importing the data
* Rendering maps with Mapnik
* Bits of code required to build geocoder
* Building simple router with Python and PostGIS
* And anything else I forgot to mention in this abstract but will talk about
OpenStreetMap -- the so-called "Wikipedia of maps" project, with thousands of contributors who edit the map data of the whole world. Unlike similar projects, the map data is completely free (both as in beer and as in speech) and thus anyone can make use of it.
Mapnik -- rendering framework, created specifically for OpenStreetMap, written in C++ and Python.
PostGIS -- an extension of PostgreSQL database, with support for many useful GIS features.
