There is a website where you can transform this kml data to surface data. You will get an endless list with stations and added surface altitude. The website is www.gpsvisualizer.com <http://www.gpsvisualizer.com/> I can't remember how to get the final file but there was still some work to do on that file.
I just experimented a bit with gpsvisualiser: 1.export model in format .kml 2. manually remove altitude from station coordinates between commands <LineString><coordinates> </coordinates></LineString>. Quite easy with help of spreadsheet. Don’t forget to add first row with headers and column with names of stations. Export as .csv (coma delimited data) file. name,longitude,latitude 0,-86.23860000000001,37.72083333333334 ... 3. use this page https://www.gpsvisualizer.com/elevation <https://www.gpsvisualizer.com/elevation> - where you may find altitude of surface above lat-long coordinates of stations from DEM model. 4. export .txt file The result should looks as this: type latitude longitude altitude (m) name W 37.720833333 -86.238600000 211.1 0 W 37.720837031 -86.238605393 211.1 1 W 37.720852666 -86.238627797 210.9 2 W 37.720836572 -86.238632999 210.9 3 W 37.720859584 -86.238609790 210.9 4 W 37.720880946 -86.238602835 210.9 5 W 37.720906567 -86.238586683 210.8 6 W 37.720922277 -86.238569001 210.7 7 W 37.720941550 -86.238578853 210.5 8 W 37.720979796 -86.238600593 210.4 9 5. convert data to valid .th file and generate .xvi file.
