Is there any a website or doc where can refer to .earth file's configuration? #2521

as we know, we can use xxx.earth file to show a map in the earth 3D model. but is there any a website or registry to illustrate how to config this file? Its format is very similar to an XML file,I want a doc that can guide me to create a .earth file. I know I can read a lot example.earth file and find the pattern and learn it,but it is a little inefficiency.

expecting everyone's reply and thank you very much!sincerely!

actually，My confusion is : I have some elevation tiles,they are some .tif pictures file. I guess I need to add their local path(because the tif picture file is in my PC) to a custome .earth file. but i have no solution about it.

There are some (admittedly sparse) docs online. What you want in a GDALElevation layer:

<GDALElevation name="Local Data">
    <url>world.tif</url>
</GDALElevation >

first，thanks for your reply and advice,Gwaldron. You're an excellent and responsible manager! but my tif file is not a single file,they are many files in a folder. so should I add more "xxx.tif" code in the tag?

This might be the best approach: https://docs.osgearth.org/en/latest/data.html#loading-a-directory-of-files

@gwaldron Thanks a lot Glenn,the approach you provided solved my problem successfully.I can finally get a good night's sleep now. By the way,The early gdal compiled gdalbuildvrt.exe may not support regular expressions. At least this version 2.1.3 doesn't work. so I found a newer version then it worked.
