Raster changes colour

Question asked by BTLeslie on Aug 13, 2014

I have a GeoTiff that changes colour when I zoom into it.  It looks like the red channel goes missing.


I'm am not using any gamma strect or fancy display scales (in fact I have tried playing with the stretch options a bit and am seeing no improvements).


The change seems to happen between scales of 1:8000 and 1:6000.


I am doing a raster QA task so it's important I see what it really looks like.


I get the same problem in QGIS or Arc does anyone know of what might be causing this problem?
