I wasn't satisfied with the quality of my Pt. Mugu scenery runways that were just aerial imagery even though the resolution was supposed to be 0.25 meters per pixel. so I created a runway model with AC3D on top of the image and added some higher resolution (one pixel equals 0.4 foot or so) imagery - that looks pretty good but I also wanted to try bump mapping on top of that so I figured that out a little and wanted to show a picture of the result for you scenery developers to consider. I think that the "concrete bumps" are overdone right now but I will keep trying different image noise with GIMP.
First image is just straight aerial imagery, no model:
Then the model with higher resolution imagery:
