re: item initally sent on 17 April. Hi All, and in particular Raul Nanclares, Many thanks to Raul for his input on my question about how to make a multiband raster file for a Landsat image (his method attached below). I tried this out and have got to the end of the first step, where I used Merge(with "Stack" checked) to combine the single band files into one file. I am doing landcover work so I am principally interested n Bands 3,4 and 5, but hope also to sharpen the image with Band 8. The merge seemed to succeed, and I now have bands 1-5 in the multiband raster file, and am using bands BGR 234 and 345 in my Displays.
I tried to superimpose and pansharpen but kept getting this message:[image: Inline image 1] Perhaps "Superimpose sensor" is not the right Tool, but I couldn't see another in the Orfeo Toolbox (?There doesn't seem to be a "search" for this toolset?). I got a similar message when I tried the Pansharpening Tool directly, without doing the superimpose first, but I admit i am not sure what files I am supposed to put in each field in these tools - I was using Ban 8 on its own, and the multiband stack file I made. Is there a Help for Orfeo, does anyone know? Or perhaps someone can see where I am going wrong and what tool I should really be using? Many thanks for any help. --Susan. _____________________________________ Raul Nanclares' inital reply (and thanks to Raul) to my first posting on this subject was: Date: Fri, 17 Apr 2015 09:26:53 -0700 (PDT) From: RNanclares To: [email protected] Subject: Re: [Qgis-user] Composite satellite images Message-ID: <[email protected]> Content-Type: text/plain; charset=us-ascii Hi Susan, first you need to use the merge/combine (i don't remember the exact name of the tool in English) located in the Raster > Miscellaneous menu. You have to check the option 'stack layers'. To pansharpen the image, first you have to see if you have Orfeo Toolbox installed and configured (in the Processing menu). If it is installed you can continue by using the sumperimpose tool (in the processing toolbox). After the superimpose has finished you can do the pansharpening using the pansharpening (rcs) algorithm found in the processing toolbox.
