This tool identifies the stack position (index) of the minimum value within a raster stack on a cell-by-cell basis. For example, if five raster images (`inputs`) are input to the tool, the output raster (`output`) would show which of the five input rasters contained the lowest value for each grid cell. The index value in the output raster is the zero-order number of the raster stack, i.e. if the lowest value in the stack is contained in the first image, the output value would be 0; if the lowest stack value were the second image, the output value would be 1, and so on. If any of the cell values within the stack is NoData, the output raster will contain the NoData value for the corresponding grid cell. The index value is related to the order of the input images.

## Warning

Each of the input rasters must have the same spatial extent and number of rows and columns.
