This is a raster or feature dataset that identifies the cells or locations to which the Euclidean distance for every output cell location is calculated.

For rasters, the input type can be integer or floating point.

If the input source raster is floating point, the Input value raster parameter must be set, and it must be integer. The value raster will take precedence over the Source field parameter setting.
