I have a four band aerial photography raster. The bands contain Red, Green, Blue, and IR data.
Using GDALInfo we get something like this currently:
Band 1 Block=2933x1 Type=UInt16, ColorInterp=Undefined
Band 2 Block=2933x1 Type=UInt16, ColorInterp=Undefined
Band 3 Block=2933x1 Type=UInt16, ColorInterp=Undefined
Band 4 Block=2933x1 Type=UInt16, ColorInterp=Undefined
The first three bands can be set to have a colour Interpretation of RGB respectively (GIS' get flaky if they're not set it seems).
But what should the ColorInterp be for the fourth, InfraRed band? Left Undefined
? Or is there a setting for IR?
