Description

Layer name:
Subject category:
Title: Catchment boundaries derived from terrian data
Feature Count: 0
Feature Type: Polygon
Abstract: 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
Purpose: To replace existing King County Watershed layer DRNBASIN with higher accuracy watersheds based on Lidar. Watersheds delineate areas that water collect and flow out to another waterbody, i.e. a Basin, River, Lake or Sound
