Hi Mach, TXP databases are paged databases so you'll need to manually page the data in bit by bit and then disgard the data once you've used it to ensure that your memory doesn't blow up. For a bit of an example that does something along these line have a look at the include/osgSim/LineOfSight implementation and in particular how it uses the DatabaseCacheReadCallback.
Getting the coords for the models will be straight forward, but I don't know if the TXP databases even store the mapping from local coords to lat/longs so the coords may not be of any use. Robert.
