Overlay Analyst

Based on the features of rasters, Overlay analysis gives different weight (the default weight is 1) to rasters and gets the weighted sum. Then it combines and output the result to a single raster layer. The output range will be determined by the union of the input data. If there are any pixel value represented as NoData, then the it will be exported as NoData as well.
