Flow Direction Raster for Maine StreamStats

This dataset consists of flow direction rasters for each 4-digit Hydrologic Unit Code (HUC) area in Maine (0101, 0102, 0103, 0104, 0105, and 0106). The cell size of each raster is 10 meters, and the eight integer values indicate the predicted direction of flow based on direction of steepest drop. The flow direction rasters may be used along with the accompanying data layers in this data release to delineate watersheds within the HUC-4 areas.
