When computing a local function, you can combine the input rasters, calculate a statistic, or evaluate a criteria for each cell in an output raster based on the values of each cell from multiple input rasters.

For example, by using cell-based statistics, the user can visualize where a desert may be encroaching over a 10-year period. From this information, a developer may choose an alternate location for a new golf course because of the lack of water supply that will occur in the near future for this area.
