Happy New Year to all!
I want to run some r.le analyses on rasters I will create from two
ortho-photo images. The newer ortho-photo is full color, so when
importing into GRASS I get the three RGB bands. So I make an image group
and subgroup with the three bands and I can do the clustering. However
The older image is a B/W tiff, so it becomes a single grayscale raster.
But the classification modules require a group with more than one band.
What's the best way to handle this?
Thanks,
Micha
