Inverted Fly-thru


Some two foot DEM data recently became available for my area and I downloaded a few DEM tiles for an area. I decided to try out the fly-through feature in the 3D. I created a fly-through path and when trying to play the fly-through the picture is inverted and the terrain image is now overhead. It's almost like I am flying under the terrain image.

Any help would be greatly appreciated.

    Hello Shaun,

    Check your Elevation Mode, and make sure that it is "Relative to Ground". This should keep you above the terrain by the elevation value that you entered. If you use the "Absolute" Elevation Mode, and your fly-through elevation is less than the elevation of your terrain, you will be flying under the terrain.

  • Thanks Bob I will try that out.
