Has someone managed to import Landsat 7 & 8 thermal images through Dragonfly?
I´ve got Landsat 4-5 working pretty well, but when I try with more recent versions it produces unexpected results. I guess there are some small modifications to the band/file naming and metadata structure.
I´ve seen it on the list for Dragonfly+ (which looks very promising!), but perhaps someone has a workaround in the meantime.
I am sorry to say that I have not yet added support for LANDSAT 7 and 8 images in the Dragonfly plugin or core libraries yet. As soon as I finish cleaning up the UWG API in Dragonfly+ (which should be pretty soon), I think the next priority will be to build objects for LANDSAT images and I will do it correctly this time (the LANDSAT 5 support in Dragonfly Legacy plugin is very hacky).
The best workaround that I can give you for now is that I think the conversion formulas for going from digital numbers for the thermal TIFF image to temperature in Celcius are pretty similar to those used in LANDSAT 7+8:
So, if you grab the right thermal image TIFF from a LANDSAT 7 image, I think you can use the same formulas to get temperature.
