File input device scaling settings

Hi, I need to know how the input scaling works with a 16 bit png. Does the altitude scaling setting “specific range” map all possible values in the input file to the specified range, or does it only map actual values in the file?

Thanks,
monks

Hi monks,

Yes. The settings correspond to:

“Natural” elevations: Values are not adjusted. The converted decimal value of the input is scaled by the current vertical height setting to get the final height
Full Range: The input terrain is scaled so that the highest and lowest values will reach the project vertical scale and zero, respectively
Specific Range: The input terrain is scaled, and the highest and lowest values are adjusted to reach the specified elevations. So for example, if you put in the height values reported under “Natural” elevations, the terrain will be identical to that (within the limits of rounding error)

Thanks Stephen, that clarifies things
