Newbie here. I've been trying to solve this for weeks and have searched and tried many suggestions from this site and still can't get this to work correctly. I'm trying to use a derived value (max) from the Value field of a raster and use it in a calculation on each row of that field, and put the results in a new field (then use that field as a lookup to create a new integer raster). I can do this easily in desktop ArcGIS, but have several hundred rasters to process, so am trying to use an arcpy for loop.
