OK, I've just pushed the code on repo.or.cz: http://repo.or.cz/w/osm-map-evolution.git but be warned there are many hardcoded things (though can be configured or easily modified). The main ideas: - the planet files are stored in a git repo (in another branch than master - the scripts warn about this and give advice) - the generation of the maps is currently tailored to focus on Caracal, my home town where I was the author of he huge majority of changes; it would be nice if this was configurable by an external file, but I expect patches - you can commit anonymously in the mob branch :-) - the generation can go back from the most recent version of the planet file in the "planet repo" down to a date or down a certain number of commits - mapnik is used for generation and the database configuration stuff surely needs checking - the main script is "gen_dated_maps" which in turn calls "gen_map" - gen_map is the rename of gen_map_Caracal and should be the generic version of the map generator - the images are created in a ne directory _maps, and can be added an optional time stamp I haven't managed to make a script to generate an animated movie of the evolution, but I did managed to make manually a movie/clip from the resulted images. I also welcome suggestions for this (and I'll come with more info on this). Any suggestions and patches are welcome! -- Regards, EddyP ============================================= "Imagination is more important than knowledge" A.Einstein
