I'm currently working on a tool for FSX/P3D that brings some freedom to the fs users in managing the static/3rd party objects on the scenery. With a minimalist GUI and openstreetmap as a background map, the program can manipulate the scenery assets (static aircraft, cars, ULDs etc...)...
Great project! Btw... this
source code helped me very much to understand how to combine winAPI + C++ + SimConnect.
FSX, FSX:SE, P3D v1-v2.5
The project I'm working on.
This is a civil and military airport in northern Poland, placed in Gdynia city...
CONCRETE 13/31 2600x60m
ASPHALT 09/27 575x30m
Navaids: ILS/DME, NDB
Total area of aprons and runways: <500 000 m2
Sorry for the confusion, mea culpa.

I agree with Kris. Furthermore, it is worth applying a rule: one object (or group of objects that are close to each other or with the same texture) - one reference point location. Especially when you export a fence that surrounds the whole airport. That helps to avoid transparency...
Remove Water Mask from your INF file, recompile the scenery and check the problem persist.
As mentioned above, in GIMP, open your orthophoto -> right click on the layer -> remove alpha channel. Save and recompile.
Make sure that in the Water Mask your land area is covered...
