Service Description: WATERSHED DETAILS: Watershed (2 ha):It is a vector dataset (polygons) representing individual capture zones or watersheds at 2ha flow accumulation threshold (i.e., 2ha is the minimum size of a headwater catchment), which comprises individual catchments with unique IDs. Each polygon represents the catchment delineated at 2ha flow accumulation threshold, which drains that area. Therefore, the Catchment_2ha layer was produced from a 1m-resolution flow accumulation raster by using a threshold of 20,000 cells. Watershed (0.2 ha)It is a vector dataset (polygons) representing individual catchments drawn at 0.2ha flow accumulation threshold (i.e., 0.2ha is the minimum size of a headwater catchment). Therefore, the Catchment_2k layer was produced from a 1m-resolution flow accumulation raster by using a threshold of 2000 cells. This means the upstream starting point (or headwater point) of stream segment was located where there is an upstream contributing areas of 0.2h. STREAMLINE DETAILS: It is a vector dataset (polylines) representing stream network at 0.2ha flow accumulation threshold (i.e., 0.2ha is the minimum size of a headwater catchment), which comprises individual stream segments with unique IDs. It was produced by splitting a stream definition raster (developed from a 1m flow accumulation raster) at each stream intersection. Each stream segment represents the catchment delineated at 0.2ha flow accumulation threshold, which drains that area.
