This tool can be used to find cells in a stream network grid that possess parallel flow directions based on an input D8 flow-pointer grid (d8_pointer). Because streams rarely flow in parallel for significant distances, these areas are likely errors resulting from the biased assignment of flow direction based on the D8 method.
