• 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.

Lucas,

As you are discovering now, high-quality elevation data is hard to find, especially for free, and especially for projects outside of the US. As you search the Internet for the data, I would recommend using the phrase "digital elevation model" (DEM), as this is the specific product you need.

As far as sources go, the USGS website will provide 90-meter SRTM data for the entire world, free of charge. The problem with this is that 90 meters may be a poorer quality resolution than what you're seeing in FSX's default setup. I could be wrong (I'm not at my FSX rig) but in either case, 90 meters is not very good and will barely make a scenery's elevation resemble the real thing, apart from large, obvious formations. I checked mapmart.com quickly and it looks like the best they have there is 90 meter as well. You may be able to get your hands on some 30 meter mesh at www.microimages.com/geodata-htm/elevation/ but it appears that this is only INPE-resampled SRTM, and comes in a proprietary format. I have worked with neither, I'm sorry to say.

My sense is that with some searching, willingness to pay, and luck, you'll be able to find some higher-resolution DEM. If you need any help finding and using the right tools, just check back here and people will be able to assist. If you choose not to purchase Global Mapper, I highly suggest VTBuilder, which provides much of Gdal's functionality, but with a more forgiving learning-curve.

Best of luck on your scenery.
