Very nice work! I remember when all land cover in FlightGear (other than runways) was desert -- not sure why Curt picked a desert texture (I think it had something to do with Prescott, AZ). Next, we were able to separate land (always forest) from water. It's come a long way since then. All the

Quite a few years ago we had a debate, because we had to choose between two sets of shoreline data: 1. GSHSS was very nicely detailed (every little cove and point), but about 1 mile off for the Great Lakes, leaving shoreline airports either far inland or floating in the middle of a lake. 2. Vmap0

When I originally added ground-use support to TerraGear many years ago, the Canada/US Great Lakes worked fine: we simply treated the water as a special ground use, used the DEM to get the elevation, clipped it against the VMAP0 coastlines, and for good measure, Curt had written code to average out

Hi, I could use a little help from one of our aerodynamics experts. First a little background. DIYdrones.com is a group of hobbiests with an interest in building hobby / open-source uav's. Actual projects vary widely, but often they are based on small electric powered foam gliders (like an "eas
