Hello guys,
I am working on a 1.2m/px photo scenery for an area that does not have SRTM data.
I would like to create a "fake" mesh map (as mentioned by Scott in another thread)by hand-painting the BSQ bmp. My problem is that I cannot find any data on which color values correspond to which altitudes.
Is there a color key, or list of RGB values, for altitudes in the BSQ bmp?
Forgive me if this has been discussed already. I did several searches but found no mention of this topic.
regards,
RJ
BSQ color key?
Hello,
I do not remeber either.
But is this
Blue is special and means 0 altitude
Then Green is varies in units of 1; Red varies in units of 256.
An example altitude of 522 metes translates to:
Red=2
Green=10
Altitude = Red * 256 + Green
The Viewer (as far as I remember) shows the altitude in the status bar or in a box. Please check if the formula above is right!

Luis
