I've got the following problems with my project. My task is complete the NDSI index calculation in the Antartic region. A problem is some pixel values are much lower than should be.
I've read about Topographic correction, but It didn't work succesfully. I didn't get higher pixel values behind the mountainous area. Luckily I found in QGIS the Topographic correction and I tried all of the topographic correction methods. In the final results I got the exact same NDSI values everywhere. (The input values was different after the topographic correction)
I also tried this toolbox, but the ArcMap crashed while the last correction was running. That happend 3 times in the same point of the progress.( https://hub.arcgis.com/datasets/fd6ed990984945d5a9827418e67f26df )
