Some additional testing from my side that hope helps someone around here ...
As previously stated, I started messing around with Sloped runways a week ago. My first objective was to be able to have the right altitudes on all objects/ POIs with an 'alt' attribute extracted from an XML exported airport from ADE. Mission accomplished, by generating an MDT02 (2 meter) mesh around my test Airport LETO (Torrejon Airbase), obtained a GeoTiff from it and matching ADE coordinates so to obtain elevation at every object/ POI... with a little help from python, I had my Airport in XML with correct altitudes matching the mesh's BGL.
Now, I am seeing that this is actually a lot more simple than I though and did not require so much "science" behind it. So here goes my tip ...
If you develop a high resolution mesh around your airport (like I did), all you have to do is set these two variables in each object/ POI within ADE:
- FLATTEN: set to Flatten
- SURFACEQUERY: set to None
If you do this, the Aprons, Runway, etc. will flatten the ground beneath so no unwanted distortions/ bumps will emerge; and with SurfaceQuery to 'None' these Objects/ POIs will leveled to ground and not depend on Taxi Point altitudes.
I know these have been probably said partially in other posts, and probably I did not fully understood, but believe me it seems a lot easier than I thought it would be.
Hope it helps.
