I have created a Raster data-set which comprises of 50 raster comprising of Landsat 7 Images. I want to calculate the Radiance for each of Raster's present in File Database automatically, by applying the standard formula provided in the Landsat 7 Handbook. This formula will be applied in Raster Calculator and Raster Calculator needs to be updated every single time and it should store the radiance calculated for separate raster layer in separately
