vector digital data
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 highest-resolution NAIP imagery available for the year of analysis. 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.govData 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.
This dataset provides high resolution land cover information for areas in Washington State for 2023. Visit https://hrcd-wdfw.hub.arcgis.com/ or email HRCD@dfw.wa.gov for more information on how the data is created, accuracy information, tutorials, user guides, and current coverage information. This land cover data is Version 3 and is still in beta.

The National Agriculture Imagery Program (NAIP) is administered by the U.S. Department of Agriculture's Farm Production and Conservation Business Center (FPAC-BC) Geospatial Enterprise Operations (GEO) Branch. NAIP acquired aerial imagery at a resolution of 1-meter ground sample distance (GSD) for the United States from 2003-2017 during the agricultural growing season, or leaf-on conditions. The images are orthorectified which combines the image characteristics of an aerial photograph with the georeferenced qualities of a map. In 2018, the ground resolution standard changed to 0.6 meter with the option for 0.3 meter data was added for consideration over coastal states. The repeat flying cycle was also changed to no longer than a 3-year cycle from its 5-year cycle back in 2003-2009. 2009 to present coverage provides a refresh of every 3-years and less responding to user needs across the United States. Each individual image tile is based on a 3.75-minute longitude by 3.75-minute latitude quarter quadrangle plus a 300-meter buffer on all four sides. In 2024 the buffer was changed to 12-meters on all four sides. NAIP quarter quads are formatted to the UTM coordinate system using NAD83.
Files are generated by compressing NAIP quarter quadrangle tiles that cover a county. MrSID compression, with mosaic option, was used. Target values for the compression ratio are (15:1) and the maximum N-levels are used. Tiles in the NAIP collection are natural color (red, green, and blue bands) or color near infra-red (red, green, blue, and near infrared bands) and may contain as much as 10 percent cloud cover per tile. More information on NAIP imagery can be found at: https://naip-usdaonline.hub.arcgis.com/

Areas of open water (i.e., lakes, rivers, estuaries, retention ponds)

Gravel
Areas dominated by gravel or sandbars, which are representative of the channel migration zone along rivers and streams.
WDFW
Tree
Areas dominated by vegetation greater than 15 feet tall.
WDFW
Shrub
Areas dominated by vegetation of heights between 5 and 15 feet (i.e., bushes, clear-cuts). Likely to contain mixed classes (Herbaceous and Built) within a polygon.
WDFW
Herbaceous
Areas dominated by low vegetation (less than 5 feet) (i.e., green or brown grass). Likely to contain mixed classes (Built, Ground) within a polygon.
WDFW
Ground
Bare ground, gravel, rock, alpine, dirt, etc. Likely to contain mixed classes (Built, Herbaceous)
WDFW
Built
Areas dominated by human built structures (i.e., buildings, roads, parking areas). Impervious surfaces account for majority of the area. Likely to contain mixed classes (Herbaceous, Shrub) within a polygon.
