Geoff,
the whole scenery build directory is
http://dl.dropbox.com/u/3028956/newScenery.tar.bz2
The process that i used for cutting up the 3sec dems was to use your
makeYSSY-1.0.4 to produce only the SRTM directory and run terrafit as
well as produce the airports.
After that everything came from shape files from ga.gov.au.
I have found that all data in the VMAP is out of position with airports
and coastal data and found that the shape files all align correctly.
There were also some changes needed to one of the terragear files to
increase the allowed build time for a tile.
~line 1187 in src/BuildTiles/Main/main.cxx
limit.rlim_cur = 300000; // seconds
limit.rlim_max = 300000; // seconds
The build command
fgfs-construct --work-dir=. --output-dir=Scenery/Terrain --lon=150
--lat=-30 --xdist=5 --ydist=5 AirportArea AirportObj SRTM2-Australia-3
LandMass Sand Rivers Lakes Freeways Trunk_Freeways Tertiary_Roads
Service_Roads Secondary_Roads Primary_Roads Towns Cities Crops
Railroads Residential_Roads
hope this all helps
Jason
PS it took 860min to build
