I'm attempting to process a number of Landsat 5 and 7 images using Apparent Reflectance via the Edit Raster Function. I've made headway as using ArcGIS versions prior to 10.2 failed to read the new metadata file format, but the output is the same indicating that the function failed somewhere (silently).
This process completes, but output is identical to the input (no change, this function modifies the input rather than creating a new output).
Attempting to setup a geodatabase to process this imagery seems to indicate the metadata still isn't being read somehow, as the gain & offset are not loaded when the images is added to the gdb.
Trying the Apparent Reflectance function a different way, it still does not behave as I expect:
Window > Image Analysis
Function Editor
Select a Landsat 5 band image > Insert > Apparent Reflectance
Result is that Gain and Bias are still unpopulated, despite the help describing that that's the point of this function. Somehow it is failing to read my images as valid Landsat imagery. I've tested it with Landsat 5 and 8 images, same result as the image attached. Anybody have this function run successfully?
Hi Clay. I am having the exact same problem trying to use the Apparent Reflectance function for Landsat 8 imagery in Arc - nothing has worked and I am pretty much giving up and just want to write a Python script that does it to see albedo. Do you happen to have those resources you mentioned or would you be willing to show an example script?
