I am trying to use the Apparent Reflectance Function in ArcGIS 10.2.2 for Landsat 8 data in order to see Albedo. I have the metadata file with the REFLECTANCE_MULT and REFLECTANCE_ADD values standing in for Gain/Bias (because that is what Landsat 8 uses as stand-ins for gain bias) and with the Sun Elevation but the values are not populating in the function and when I enter them manually I get:
"The function could not be inserted. The input or output arguments are invalid."
At first I tried it on a tif file with more than 13 characters so i converted it to a float type with far less than 13 characters but got the same result. I'm using 10.2.2 and have already got the Landsat 8 patch.
If this function is bunked, is there a simpler way to do it in Python?
The links to the tool:
Apparent Reflectance Raster Function | ArcGIS Blog
ArcGIS Help (10.2, 10.2.1, and 10.2.2)
Any ideas?
And you ruled out Tristan and Simon's question/comment towards the very end of the blog post as applying?
Ruling out using the REFLECTANCE_MULT/REFLECTANCE_ADD for Landsat 8 as gain/bias you mean? what other values would you use?
So for Landsat 8, the gains/bias are all set to the fixed number of 2.0000E-05 and -0.1 .
From that thread apparently, they are fixed
