• 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.

How to generate BGL from DEM?

Hi all,

I opened a DEM file in GlobalMapper, and exported to a GeoTIFF file.
I want to use resample to build BGL. The problem is : resample only support WGS84 format, but my GeoTIFF file format is WGS72. How to solve it?
or else, would you please point me another way to generate BGL from DEM?

Thanks in advance,

Look at the last couple of steps in this post...

Mountain Maker

And learn to use SBuilder... because the DEM to BGL is just the beginning... then you want coast lines and objects and grass and trees and roads and rivers and and and....

Have Fun... its a ton of fun...

Basically SBuilder sits in front of of the SDK and makes life a whole lot easier... but if you look at that post... you will see there is another step that will take you the SDK route...

Before you export from Global Mapper, open the configuration tool, and on the projection tab select geographic projection and wgs84 datum from the pull down lists, then OK and it will be adjusted as needed. on the status bar bottom right it should show GEO (WGS84). Now do your geotiff export 16 bit elevation and resample should accept it.

Thanks

Hi, scott, you are quite right. I did follow your sugestion and resample accept it.
And 3DEM is indeed a good tool. I using it to open the DEM file and save as GeoTiff DEM, the resample accept the .tif file too.
Thank you, scott and CrashTestDummy, very much.
