Map algebra between two images

Discussion created by liangcun on Dec 16, 2016

Hello all,


I have two geotiff images (exposed as image services) with same extent and resolution. Now I want to perform map algebra operations (e.g. minus, plus, and mean operation) between these two images on a pixel-by-pixel basis. Should I use "Geoprocessor" Class or "Raster Function" Class? Any ideas or experience to share ? Thanks!
