Watershed boundaries derived from terrain data [Washington (State)--King County]
Description
For more information about this layer please see the GIS Data Catalog . DRNBASIN is replaced with a higher detail TOPO_CATCHMENT. The difference between the two is DRNBASIN was digitized from existing paper maps based on USGS quad maps in the early 1990s. While the TOPO_CATCHMENT was produced using Arc/Info GRID Watershed commands on 6 foot cell GRIDS built from LIDAR ascii ground model data. Topo_Catchment is higher in accuracy then DRNBASIN
