Other VSP Planning and Mapping Resources

We partner with other state agencies to provide mapping resources for planning under Washington's Voluntary Stewardship Program (VSP). Get resources to help you develop and manage your VSP.

Our resources

We maintain the spatial datasets described here in order to better describe the diverse natural and cultural environment. As a public service, we have made some of our data available.

One of the spatial datasets available is Water Resource Inventory Areas (WRIA) for Washington State at 1:24,000 scale. WRIAs are being used as the planning unit for the VSP.

Other state agencies

Washington state geospatial portal

Washington provides a geospatial portal where you can find data, products, and services available in the state. The web site contains a data catalog in which you can find public-facing GIS data layers and related geospatial information produced and maintained by state agencies. The data are also organized by state agency.

Map data

Light Distance and Ranging - LIDAR

Light Distance and Ranging (LIDAR) is a relatively new technology that employs an airborne scanning laser rangefinder to produce accurate topographic surveys of great detail.

LIDAR can be used, in conjunction with other data, to identify depressional wetlands, frequently flooded areas, and geologically hazardous areas, as well as other features. It can be used in land-use planning, archaeology, agriculture and others. In 2015, Washington Department of Natural resources (WDNR) initiated a new LIDAR program and has begun collecting, and processing existing LIDAR data and collecting new data in priority areas.


High Resolution Change Detection

High Resolution Change Detection data, generated by the Washington Department of Fish and Wildlife (WDFW), may be helpful when monitoring the effects of activities on agriculture and the vegetation in critical areas.

WDFW can detect small scale changes in vegetation such as a decrease in the canopy cover of woody vegetation and an increase in semi-pervious or pervious surfaces. This data can be used as a monitoring tool for VSP counties for which analyses are completed. WDFW has completed HRCD maps in 14 watersheds in Washington 2013.


Data limitations

  • HRCD must be overlaid with a critical area layer from the appropriate year to detect change.
  • The data in the non-Puget Sound watersheds are not as robust as data collected in the Puget Sound area. WDFW may be completing more analysis in these or new watersheds in the near future.
