Hi, A member of the OSM forums and of the German & Polish communities, Marek Kleciak, asked me to invite interested developers to discuss the tagging and implementation of the schema used for 3rd dimension information (height/altitude) in OpenStreetMap, and also historical information. A couple of schemas have already become popular and Marek and others would like to find the best representation. They are getting down to details like building roof windows and tree species to make accurate 3d models directly from OSM data.
Unfortunately there's no mailing list where this is discussed, that I know of, instead discussion happens on the forums and wiki: http://wiki.openstreetmap.org/wiki/DE:OSM-3D http://wiki.openstreetmap.org/wiki/DE:OSM-4D#Tagging_2 (the pages have English versions, but they are not fully translated yet, but apparently it's Ok to use English on these German pages) http://wiki.openstreetmap.org/wiki/Roof_table (again German/Polish versions may be more complete) http://wiki.openstreetmap.org/wiki/User:Viw/OSM3D http://wiki.openstreetmap.org/wiki/User:Aschilli/ProposedRoofLines and others. Marek would particularly like interested developers to help in the implementation of different roof types display and other 3d features in the projects: * kendzi3d (JOSM plugin) * osm2world (osm2world.org) Finally I'm sure a number of OSMers oppose adding too much detail to the OSM database and especially some of the 3d modelling features don't seem to fit our data model (which is very 2d + tags). Personally I think it's unavoidable that all of these details are going to be added at some point, though.
