Elevation Maps

To add an elevation map, make a copy of the file

C:\Program Files (x86)\Tacview\Data\Terrain\Custom\CustomHeightmapList.xml

into a subfolder of your choice inside

%PROGRAMDATA%\Tacview\Data\Terrain\Custom\ or

%APPDATA%\Tacview\Data\Terrain\Custom\

You can rename the XML file as desired.

Open the XML file which is now in your %PROGRAMDATA% or %APPDATA% folder. Following the instructions and examples in the file, add a new entry for your elevation map. Place your elevation map file in the same folder. Re-launch Tacview.

Go to Options→Terrain and ensure that Real Terrain is selected.

Tips

• If your elevation map is unsigned, add the flag <Signed>false</Signed>.

• AltitudeFactor and AltitudeOffset serve to convert the raw values stored in the elevation map into the final altitude used by Tacview. If not specified, the default values are

  AltitudeFactor = 1.0 and

  AltitudeOffset = 0.0

  The conversion is performed as follows:

  finalValue = (altitude * AltitudeFactor) + AltitudeOffset

  rounded to a signed 16-bit value.
