• Which the release of FS2020 we see an explosition of activity on the forun and of course we are very happy to see this. But having all questions about FS2020 in one forum becomes a bit messy. So therefore we would like to ask you all to use the following guidelines when posting your questions:

    • Tag FS2020 specific questions with the MSFS2020 tag.
    • Questions about making 3D assets can be posted in the 3D asset design forum. Either post them in the subforum of the modelling tool you use or in the general forum if they are general.
    • Questions about aircraft design can be posted in the Aircraft design forum
    • Questions about airport design can be posted in the FS2020 airport design forum. Once airport development tools have been updated for FS2020 you can post tool speciifc questions in the subforums of those tools as well of course.
    • Questions about terrain design can be posted in the FS2020 terrain design forum.
    • Questions about SimConnect can be posted in the SimConnect forum.

    Any other question that is not specific to an aspect of development or tool can be posted in the General chat forum.

    By following these guidelines we make sure that the forums remain easy to read for everybody and also that the right people can find your post to answer it.

Hello:

If you only need to "flatten" the aerodrome at an assigned elevation which matches the surrounding terrain, this is done with a "flat" airport background vector flatten polygon.

If you need to make a slope from the aerodrome down to the surrounding terrain, this is done with a "sloped" airport background vector flatten polygon.


For more info on these procedures, see the manual for Airport Design Editor (aka "ADE"):

Also, see this thread (and other such threads here at FSDeveloper via the forum "Search" feature):

Hope this helps ! :)

Most developers would use SBuilderX to blend the mesh to the flatten with sloped flatens (sometimes triangles). You can use SBuilderX with FSUIPC to get the right point locations into SBuilderX, and TCalcX for the needed elevation of each point.

The default airport flatten isn't blending in with the mesh. You can use ADE to make flatten polys around it to blend the edges in with the surrounding terrain.

Select "edit individual points" and right click on each of them and "move aircraft here", then select that vertex and "set to FSX altitude".
 
Have a hollow square with your airport in the middle. The middle verts have the airport altitude, then you put a vert every 100m or so around the outside and do the above. Unless there's large undulations in the scenery, this'll work fine. I've had to to it with nearly all my airports.
 
Enter the source and destination directories, or just "." for the same folder.

And in "xxxx.tif" needs to be the same file name as your DEM.
 
There's something wrong with how the coordinates are embedded into the Geotiff.

I get:
ulxMap=455000
ulyMap=4391200
xDim=25
yDim=25

I would use the 5m mesh around the airport and sort it out with the polygons like I mentioned beforehand. That or someone else will have to have a look at this. It's beyond my capabilities, I think the GEOtiff is broken.
 
congrats nice you have got the hang to the mesh, if you are interested in the terrain developing there was a tutorial about photoreal scenery creation it would help a lot to understand how this work I would have to link the tutorial to somewhere because the old links are dead, it's an old tutorial.the tutorial is "manual para realizar escenarios foto-realista para fsx" from Albserto Sánchez. It was in the same site you get the mesh tutorial. Airhispania.
