I am processing a multispectral project. Images were taken with multiSPEC 4C and the calibration target by AIRINOV which albedo values are already known by the manufacturer. Whenever I calibrate the Green band everything works okay, but I have problem with the other channles. The software claims that:
Warning]: Warning w9020: GDAL error <1> TIFFFetchNormalTag:Incompatible type for “RichTIFFIPTC”; tag ignored
[Error]: This image is not compatible with the 'multiSPEC4C\_3.6\_1280x960 (Red)(2)' camera.
I tried with two different datasets from different periods of time and the error remains!
Could you please explain why there are 8 calibration images for 4 bands? Is the camera taking 2 images per band? How could I recognize for which band a particular image has been taken?
I would very much appreciate it if you shed some light on the calibration problem I have.
