I've seen that you've found a solution, but some comments anyhow:

5. Pansharpened bands 4, 3, 2 using band 8 as the panchromatic band with the IHS method
Have you seen that brovey is also available as a method in i.pansharpen ?
7. Result: An image that is entirely gray (I found this link that says to use i.fusion.hpf, but following those instructions, I get “'make' is not recognized as an internal or external command, operable program or batch file.”
This means that you do not have make installed. How did you install GRASS GIS ? Maybe you need to install a specific development package ?
From searching online, I have found that the i.pansharpen module doesn’t take 16 bit imagery (which Landsat imagery is) but rather 8 bit. I found this link (http://gis.stackexchange.com/questions/39174/how-to-color-balance-false-composites-of-pan-sharpened-landsat-images-in-grass/67319#67319) that says to rescale the image. I attempted this twice: 1. When I run it on the bands produced after running the i.landsat.toar module, I get numbers such as min=-0.00813278402972343 and max=1.58301384751301. After rescaling the images to 0-255 and proceeding with step 3 I end up with an entirely white image.
How did you rescale ? And what does r.info give you on the rescaled maps ? Moritz _______________________________________________ grass-user mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/grass-user
