Geometry Type: esriGeometryPolygon
Description: The data is intended to help assess patterns of land cover at a variety of scales. The polygons represent areas which have similar land cover type. Landcover information was derived from 3ft NAIP imagery flown during leaf-on seasons. This dataset is still in Beta. What that means is that the tree, water, and gravel (streambed) classes are quite reliable; the built (impervious), ground, and low vegetation (grasses and shrubs) land cover classes tend to get mixed in with each other. Each WRIA/county varies in accuracy - the user needs to visually inspect a few areas to confirm the needed classes are still of use with the current accuracy.
We are constantly improving the landcover accuracy with new versions. If you would like to be informed when new data is available for your area, email HRCD@dfw.wa.gov
Data have been created for areas in Washington as funding allows: visit https://hrcd-wdfw.hub.arcgis.com/ for information on past and current funding sources.
