At one of our meetings maybe more than two years ago Ralf presented to me what later ended up as "v.contri" GRASS module in "terragear-cs". It is supposed to be an adaption of exactly the same triangulation as in "fgfs-construct". He was able to prove successful triangulation of a slightly complex airfield layout (something like EDDK), thus we may assume that it's functional at least in general, but I think he never threw large maps at it. > http://www.cs.cmu.edu/~quake/triangle.exact.html .... from a certain perspective, this looks like opening yet another can of worms ;-) > I want to finish my fgfs-construct rework before looking into GRASS modules > again, but I was wondering if we have documentation / sourcecode on how the > OSM data was imported / converted to shapefiles on the mapserver. I've been using "osm2pgsql" for years for importing The Planet Dump into PostGIS and so far I'm quite satisfied. After the bare import I'm using a custom script to separate the various road types into distinct tables/layers, something like: landcover=> SELECT osm_id, access, admin_level, z_order, way_area, wkb_geometry landcover-> INTO osm_motorway landcover-> FROM planet_osm_line landcover-> WHERE highway LIKE 'motorway%' landcover-> AND ST_GeometryType(wkb_geometry) LIKE 'ST_LineString'; That way I don't have to query the entire "planet_osm_line" if the user selects a large scale which doesn't include all the residential roads. I'd certainly extend this to "SELECT * [...]" if required ;-) Well, and for the Scenery building I'm just using this script - see the bottom for ${ROAD_TYPE} = "OSM": http://mapserver.flightgear.org/git/gitweb.pl?p=terragear-cs;a=blob;f=src/Prep/OGRDecode/process.sh No Shapefiles at work here.
