A BSD licensed javascript implementation of some of the mapnik Layer, Rule, Style and symbolizer
classes (implemented mainly by eye-balling the XML and reading the wiki).
Also javascript classes to take XML from the OpenStreetMap API and turn it into GeoJSON-ish things.
Also javascript classes to make using Array.filter more sane, and slightly SQL-ish.
Nowhere near feature complete. There is an initial attempt to implement text rendering,
which is where things should get interesting.
OpenLayers has a similar set of classes for styling vector data, and Cartagen also explores
similar ideas.
TODO:
- proper projections (right now things just get squeezed into squares)
- more symbolizers (text, point, etc)
- try an SVG renderer instead of canvas (DOM is handy!)
- load and parse mapnik-ish xml files (URLs for sources?)
- load and parse cascadenik files (CSS++)
- use something like YQL to transform the XML to GeoJSON on a server?
