[Qgis-user] satellite band manipulation

[Brad Nesom]

I am interested in applying the theory described in the linked article to a
satellite image.

My goal is to depict hot spots on the earth surface. My problem is I am not
very mathematically inclined and I don't program from sctratch well either.

I understand that I need to convert the values in the band I am interested
in (band 7). I am interested in band 7 because the values in th shortwave IR
I am interested in are sharp spikes running around 100DN higher than
anything else in the image. So they are visible in daytime on this band. I
am not sure about the values in band 7. What I need to convert from? I
believe I need to use Planck's radiation equation. The document I have
linked to goes way over my head. I have a good assortment of software at my
disposal to accomplish this once I understand what I need to do. Qgis may or
may not be the tool to do this with.
I appreciate any direction or help with this project.
Brad
