Hi, I know I'm a little behind with my ENVI version (I don't see our institute upgrading for quite awhile). I'm trying to generate a Land Surface Temp map using Band 10 (keeping it simple) in Landsat 8. I'm not exactly sure of the workflow, and seem to get a few different directions from different sources. If I understand right, I first need to convert to radiance, then TOA reflectance and possibly factor in emissivity using NDVI or some other classifciation method (I'm not sure if this last part is necessary for what I'm doing, as the surface types I'm evaluating are fairly similar) I'm not exactly sure how to do all of this using ENVI 4.5, though--any general sense of the workflow (I know I can't automate it because of the version) would be helpful. Thanks! --s
