I need to create a temperature map from Landsat 8. I found an algorithm that explains how to do it in ArcGIS:
Unfortunately I can’t use this method, because the “local function” (that is used in Step 3 - “To calculate the natural log, you need to use local function”) is blocked in my version of ArcGIS. The program gives: NOT LICENSED "This raster function requires a license" It’s strange, because now I use the trial version of ArcGIS 10.2.2 (that gives all possibilities for 2 months), maybe I can find this function somewhere?
Also I tried to realize this algorithm on the permanent version of ArcGIS 10.0 But here I can’t find the Raster Function Template Editor" (from Step 1 – B) (I don’t have any “Commands” in Customize >>Raster). So, two problems in the both versions of ArcGIS that I can’t solve.
But as I understood, this method explains how to create a Function chain which can be used for any Landsat 8 for preparing a temperature map. Maybe some special script for ArcGIS for this purpose has been developed?
Or maybe you can advise how I can create a temperature map from Landsat 8 in ArcGIS (by dint of this method or other). Also I have ENVI 5.0, so I’ll be glad advises for method by dint of ENVI as well.
