Hi, no worries,
the Geotiff has no calibrated elevations upon export, it just returns the 8-bit 0-255 numbers for an RGB image when viewed in image processing software. This work was done last July, after calibration the GPS elevations could be seen across the image, numbers surrounding 1850 amsl.
Now, when the Geotiff is viewed in an image software, the surface numbers are not elevations, but the 0-255 8-bit color table numbers.
DD is used on monthly basis here when required, to show this now a monthly subscription would be required for a few minutes work.
I was curious if others have seen this, a calibrated elevation surface not returning the calibrated elevations upon Geotiff export, but the 0-255 8-bit color table numbers, is this a bug or does not DD export out to Geotiff the calibrated surface elevations? Or perhaps a setting was missed when exporting, to ensure the calibrated numbers were output.
