Committers and Cartographers was the name and theme selected for the first Mapnik Code Sprint. Grown from the seed of an idea at the OpenStreetMap State of the Map conference in Girona, Spain, July 2010. It germinated on the Mapnik-Devel list to grow into an event on two continents.

Date

Friday, 24 September 2010 - Sunday, 26 September 2010

Location

MCS01 will be / was held in London, England.

Schedule

This will be a full weekend of Mapnik fun. For details see the schedule.

Code

Plan here for code to write and bugs to squish. Please add your thoughts. Discuss. Plan.

Cartography Wish List

Cartography wish list.

From Steve Chilton's SotM presentation:

  • respect the layer tag implicitly
  • names for lower roads should not appear where other roads pass over them
  • iterate alternative label placement
  • apply point within polygon labels
  • allow rotation for icons
  • accept SVG icons (Done)
  • apply variable widths to canals and rivers
  • apply vignettes inside polygons
  • produce spread text labels
  • different casing either side of roads (Done as patch for 0.7.1? see offset lines #180 )
  • text labels either side of a line
  • more Natural Earth data at low-zooms (May apply more to OSM style than Mapnik-core)
  • add your advanced cartography requests
  • as it's already able to replace certain strings in the filename of a Symbolizer, other parameters should be changeable too. Say: I want to define a Template for a Symbolizer in the Stylesheet, but define its parameters (color, width, etc.) from database columns.

Cascadenik

Rob's going to be working on Cascadenik:

  • adding all the currently supported symbolizer attributes
  • supporting Mapnik2 alongside 0.x
  • supporting the new parameterized symbolizer attributes
  • merging the -xmlbad branch to trunk
  • cleaning, testing, and fixing bugs
  • fixing mapnik bugs uncovered by the above :)
  • one being #612 (dane will try to close during sprint)

Profiling

Fred's interested in performance:

  • how long did it take to render this?
  • how much time was spent acquiring the data,
  • how much was spent processing each layer/style,
  • etc
