setting Z-scale

[Ken Hickey]

g'day   Does anyone know how the Z-scale % values relate to actual z-values in a height layer? I have a DEM that I am looking at in 3D perspective view (height values in meters), I want to set vertical exaggeration to 1, but I can't make sense of the z-scale values. Visually, a x1 vertical exaggeration seems to correspond to ~ 500% Z-scale   cheers Ken Hickey ------------------------------------------------------------------ Kenneth Hickey Mineral Deposit Research Unit (MDRU) Department of Earth and Ocean Sciences University of British Columbia 6339 Stores Rd, Vancouver, BC  V6T 1Z4, Canada phone +1-604-822-3765; Fax +1-604-822-6088 email: [EMAIL PROTECTED]   .
