[GRASS-user] Processing NAIP images

[Pedro Camargo]

Hi,
       I am trying to generate land use maps (looking to identify roadways
only, actually) using NAIP imagery.

       Since I am using the pre-compiled GRASS, I do not have MrSID inside
GRASS, so converted the images to TIFF using QGIS.

      I believe I can use i.maxlik or something like that, but I do not
know how to start.  It keeps asking for groups, but I do not know what is a
group image.


    I googled a lot on this and looked into several tutorials, but still
did not figure out how to start  this.  I have been educating myself
through a few papers, but I guess I still need to find a good summarized
tutorial on how to do this with multi band images such as NAIP.

Does anybody have ideas to help?

Thanks,

Pedro
