No, I didn't know. When I talked to Brian Schack about this topic, the conversation somehow got lost (and I do feel guilty in some way ....). As far as I can remember the biggest obstacle was set by Atlas's tile schema being organized alongside FlightGear's Scenery tiling schema, being slightly different from what WMS tile servers typically provide. Actually I'm unable to afford the time for providing the introduction into the logic behind WMS(-C) and related protocols, but there's plenty to read at OSGeo and related projects (start at TileCache for example). BUT I'd be willing to set the tile server up - simply because I'm convinced that this is "the right thing to do" about serving map imagery from a server .... well, actually the entire infrastructure is already in place, because I've been doing this sort of stuff for years, I'd just have to compile the Atlas imagery into a suitable format. Actually there are many functional OpenSource WMS clients available, you don't necessarily have to write one from scratch. KDE Marble has one, QGIS has one, even GDAL includes a WMS client implementation: http://gdal.osgeo.org/frmt_wms.html > The ONLY 'sample' WMS server written into it was > wms.jpl.nasa.gov, which, as you may know, no longer > offers full public WMS services...

Please negotiate with Brian - I think he's still the Atlas maintainer - in order to prevent forking and/or duplicate work and keep me posted, if required. > It could be easily modified to use "EPSG:900913" if > that is preferred... I'll leave this to you. The benefit of EPSG:900913 is to be conformant with many well-known public tile services. If you manage to automatically create requests like this one (_very_ long line): http://mapserver.flightgear.org/tc/?LAYERS=tarmac&TRANSPARENT=true&FORMAT=image%2Fpng&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&STYLES=&SRS=EPSG:900913&BBOX=714227.59136875,6653078.93995,724011.5309875,6662862.8795688&WIDTH=256&HEIGHT=256 .... then you've probably overcome most of the trouble. > And as indicated, I hope later airport and navaid > overlays could be added via say &LAYERS=... or something, Sure, various solutions are already in place, they're just waiting for being used :-) > What is the GetCapabilities URL?
