Thanks, Bill, but to be honest, I've cut the photoscenery out in some of the more populous places (with a 0,0,0, mask) on the base and am letting the original autogen show through, then augmenting with hand placed autogen and generic buildings that keep with the spirit of the area. LOL...less accurate, but I don't have to build 500 buildings.
Global Mapper was a good purchase. I'm tempted to get Manifold so I can control the elevation a bit better, especially around the water. I think there should be a "This is water, stupid, it doesn't run uphill" flatten.
Shouldn't be too much longer Trans. I recently re-found a coastie pilot (Dauphin) that worked with me on Whiting Field. He's stationed in Houston and he likes it a lot too.
Best,
Jim
