I had a weird issue at NZFH – Fox Glacier’s airfield that seems to be used by a tour company. It had a couple of really steep hockey stick jumps in the middle. I thought I had screenshot it, but I can’t find it now.
Here’s a look at how X-Plane default scenery handles this:
It’s dead flat. Probably because it’s unuseable for some reason with the terrain modelling from the data, so they just flick a switch and smash it flat. I used to fix this by trying to change settings, or just using the brute force option of flattening the airport also.
Here’s a look at it on Google Maps:
Here’s a rough guide to the elevation profile:
The runway rises steadily and then towards the ramp at the end, it rises slightly more steeply.
No amount of smoothing or tweaks to Ortho4XP seemed to have any affect at all, so I decided to make a mesh patch for the runway and ramp.
In order to patch the mesh to smooth it out, I used a couple of tools:
Java Open Street Maps – a tool that lets you edit a patch together https://josm.openstreetmap.de/
Google Earth Pro – a powerful desktop tool to get a profile of the height of the ground to patch into the mesh using JOSM. https://www.google.com/earth/versions/
Patching together a simple array of polygons, here’s the result:
The ramp and buildings at the top site at 178 metres, with a little drop and then steady decline down to 150 metres.
If you know of other airports that are troublesome, let me know. If it needs fixing in my mesh, I’ll try to catch it.
