![]() ![]() By default, the resolution will be set to the resolution of the input cost raster. The resolution of the raster can be controlled with the Cell Size environment. When the input source data is a feature class, the source locations are converted internally to a raster before performing the analysis. A source raster can be created using the extraction tools. The value 0 is considered a legitimate source. ![]() Cells that have NoData values are not included in the source set. When the input source data is a raster, the set of source cells consists of all cells in the source raster that have valid values. The input source data can be a feature class or raster.
