[GRASSLIST:10153] Re: importing EDOQ LUT

[Martin du Saire]

Thanks for your quick response,

The problem is that imagename.red, imagename.green, and 
imagename.blue resulting from r.in.gdal, are identical grayscale 
images.  Their histograms are exactly the same, so the composite ends 
up being grayscale...it should be RGB right?  But r.composite would 
produce an RGB raster map only if xxxx.red, xxxx.green, and xxxx.blue 
are distinct, right?

Is there a problem with the .jpg, or am I importing it incorrectly?

Is there supposed to be a look-up-table associated with the image 
that I use to generate the  xxxx.red, xxxx.green, xxxx.blue?

Thanks.
