Hi everyone (again),____

I am having trouble exporting a composite RGB image into a GeoTIFF
format that I can open in Global Mapper, Photoshop, or other
programs. This is using Landsat 8 imagery. I am able to open the
composite image in QGIS, but not in Global Mapper or Photoshop. ____
__ __
Below is a list of steps that I took to get the image. I am unsure
of what settings to use when using r.out.gdal to export my image so
that it works in other programs. I am using GRASS 7.0.4.____
__ __
__1. __Import Landsat 8 imagery____
__2. __Convert the DN to reflectance/radiance____
__a. __i.landsat.toar input=LC81100362016082LGN00_B
output=LC81100362016082LGN00_refl
metfile=LC81100362016082LGN00_MTL.txt____
__3. __Perform pansharpening with i.fusion.brovey addon____
__a. __i.fusion.brovey -l
ms1=LC81100362016082LGN00_refl2@Osaka
ms2=LC81100362016082LGN00_refl3@Osaka
ms3=LC81100362016082LGN00_refl4@Osaka
pan=LC81100362016082LGN00_refl8@Osaka output_prefix=brovey
BTW: this method is superior (the addon can be installed with
g.extension):
https://github.com/NikosAlexandris/i.fusion.hpf
The addon is not in the addons repository, so you cannot install it with
a simple g.extension i.fusion.hpf. In GRASS 7.2 / trunk you can install
it with g.extension by downloading the source code and pointing the url=
parameter of g.extension to the source code directory.
I hope that the code will be put into the addons repository, soon.
from https://grass.osgeo.org/grass72/manuals/g.extension.html
Online repositories: GitHub, GitLab and Bitbucket
For well known general hosting services, namely GitHub, GitLab and
Bitbucket, g.extension supports the download of a repository as a ZIP file.
Here the user only needs to provide a base URL to the repository web page
(with or without the https:// part). For GitLab and Bitbucket, the latest
source code in the default branch is downloaded, for GitHub, the latest
source code in the master branch is downloaded. Of course, a user can still
specify the full URL of a ZIP file and install a specific branch or release
in this way (ZIP file mechanism will be applied).
Right. Forgot about this.
g.extension i.fusion.hpf url=https://github.com/NikosAlexandris/i.fusion.hpf
works perfectly in 7.2 and trunk, but not yet in 7.0 which is still the
official stable release.
Thanks for the heads-up !
Moritz
