Hi Drew,

TerraGear builds tiles for the FlightGear simulator.  These tiles are 
based on a WGS84 scheme.  However, it doesn't yet deal well with large 
amounts of imagery and FlightGear also does not deal well with paging 
imagery.  99.9999% of the existing scenery is built from SRTM data + 
vector land use/land cover features + generic/representative textures.

We would like to explore imagery based scenery at some point, but time 
is always the limiting factor.  If you have good imagery and want to 
pursue this from a development angle, let me know.

Regards,

Curt.
