It can therefore overlap impervious layers.High vegetation is distinguished from low vegetation based on crown, texture, and derived height models. Leveraging stereo imagery produces results using 3D elevation models used to aid the distinction of vegetation categories. Distinguishing low from high vegetation is based on a 5m threshold, but this is not always feasible, especially in areas where heavy canopy prevents a visualization of the ground. In these circumstances, high vegetation will be given the priority over low vegetation.

Use this web map to link to other geospatial datasets available through county and city sites (Not comprehensive). May need to zoom in to see the participating cities. The county boundaries and city points were published by Washington State agencies and downloaded from geo.wa.gov. Locations are approximate, and no warranties are made regarding this data. The canvas basemap has been compiled by Esri and the ArcGIS user community from a variety of best available sources. Want to have your data site listed? Contact the Geospatial Program Office.

Download the entire dataset: https://fortress.wa.gov/dfw/public/PublicDownload/Habitat/HRCD/HRCD.zipThis dataset includes changes in land cover throughout Washington State, specifically areas of tree loss and development. Changes are represented as polygons and include qualitative descriptions and quantitative assessments of changes. Attributes provide details about causes of change (Change Agents), types of changes observed (e.g. canopy loss, impervious surface gain), area of change, and time period for when the change occurred. The change locations were identified from analyzing high resolution (1-meter) NAIP imagery, allowing changes as small as a single tree or new home to be identified.This dataset covers most of Western Washington and several counties in Eastern Washington. Coverage is split along county and/or WRIA boundaries and the time periods for change locations vary by county and/or WRIA. All areas in the dataset were assessed for changes between 2011 and 2017; additionally, some locations include changes as early as 2006 or as recent as 2021.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 or extent information.This dataset is updated about once a year with more recent years of change, new counties / WRIAs, or both. This copy of the data was updated in January 2024.

This was created using the Feature Outline Mask tool in ArcGIS 10.2.2. The feature outline mask was applied to the State of WA boundary layer and a tolerance of 5 points was used. Then a polygon was created which is the extent of the world. Finally, the mask was used to cut a hole in the world extent polygon. This is the result you will see in this layer.

Due to the unprecedented need for near real-time information, WDSOT is providing daily travel trend data from permanent traffic recorders as soon as it is available. However, this allows for the application of only minimal levels of quality assurance, and therefore the data should be used with caution. Additionally, this data feed will be terminated as soon as the current crisis has resolved, and users will be directed to traditional reporting system such as WSDOT’s Traffic Data Geoportal: https://www.wsdot.wa.gov/mapsdata/tools/trafficplanningtrends.htm.

The Regional Trend, PTR Site Trend, and Active Transportation PTR Site Trend tables have been populated with data from 3/1/2020 forward. Each morning at approximately 10:00 AM Pacific, data from the prior day will be added. At the same time, data from the two, three, and four days prior will be refreshed in order to address initial gaps (with the most significant initial data gaps usually occurring on Friday, Saturday, and Sunday).

Additional spatial reference datasets are also provided – PTR Site Location, Active Transportation PTR Site Location, Urbanized Area, WSDOT Region, and State Boundary. The Regional Trend table can be joined to Urbanized Area, WSDOT Region, and State Boundary using the Jurisdiction field. The PTR Site Trend table can be joined to PTR Site Location using the SiteID field. Finally, the Active Transportation PTR Site Trend table can be joined to Active Transportation PTR Site Location using the SiteID and LocationName fields respectively.

The WSDOT Traffic Volume Trend data is available for download from the Washington Geospatial Open Data Portal. Download the Regional Trend, PTR Site Trend, and Active Transportation PTR Site Trend tables as CSV and Esri File Geodatabase tables and the reference datasets as CSV, KML, Shapefile, and Esri File Geodatabase feature classes.

The Public Land Survey System (PLSS) Grid - Line is linework derived from the master coverage of the PLSS maintained by the Assessor's Office. This dataset only contains linework and attribute information for townships, ranges, sections, quarter sections and quarter quarter sections and government lot lines. It is compiled from recorded surveys and plats, coordinates and linework supplied by private surveyors, Snohomish County Public Works Survey, cities, Washington State Department Of Natural Resources (DNR) and the United States Department of the Interior - Bureau of Land Management (BLM). Standard BLM methods are used to construct the aliquot grid. In coastal areas, the aliquot grid may not apply for many of the coastal sections, it has been constructed for the purposes of land title and defining map extents for automated routines.

In 2007, Washington State legislators requested a trails database, but funding to complete that statewide project was not made available at the time.In 2009, the Federal Government outlined the need for trails database schema in their Data Standards Review Committee, stressing the efficiency in management decisions that a streamlined database can provide.“The collection, storage and management of trail related data are important components of everyday business activities in many federal and state land-managing agencies, trail organizations and businesses. From a management perspective, trails data must often mesh closely with other types of infrastructure, resource and facility enterprise data.”In 2014, the Washington State Office of the Chief Information Officer's (OCIO) Geospatial Program Office acquired a Nonhighway and Off-Road Vehicle Activities (NOVA) Program grant through the Washington State Recreation and Conservation Office (RCO) giving the OCIO initial funding to develop a statewide trails database based on Federal Geographic Data Committee standards. Using the same standard for all trails data will allow land managers and recreational users throughout the state to access and use the data regardless of administrative boundary."Data standards will make it easier for trail information to be accessed and exchanged and used by more than one individual agency or group…Ease in sharing data increases the capability for enhanced and consistent mapping, inventory, monitoring, conditions assessment, maintenance, costing, budgeting, information retrieval, and summary reporting for internal and external needs.”Along with streamlining data and facilitating efficiency in management practices across agencies, the database will provide a source of trails information that is open and free to the public.The 2016 State Legislature provided additional funding from the Nonhighway and Off-road Vehicle Activities Account to the Office of the Chief Information Officer to continue work on the database.Additional details about the project can be found here:http://rco.wa.gov/recreation/WashingtonStateTrailsMap.shtml

Unincorporated Urban Growth Areas (UGA) as defined by the Growth Management Act (GMA). The annual update is conducted by collecting UGA polygons directly from each of Washington's 39 counties. As of 2025, there are 27 counties with UGAs.All UGA polygons are normalized against the Department of Revenue's (DOR) "City Boundaries" layer (shared to the Washington Geoportal a.k.a. the GIS Open Data site: geo.wa.gov). The City Boundaries layer was processed into this UGA layer such that any overlapping area of UGA polygons (from authoritative individual counties) was erased. Since DOR polygons and county-sourced UGA polygons do not have perfect topology, many slivers resulted after the erase operation. These are attempted to be irradicated by these processing steps. "Multipart To Singlepart" Esri tool; exploded all polygons to be individualSlivers were mathematically identified using a 4 acre area threshold and a 0.3 "thinness ratio" threshold as described by Esri's "Polygon Sliver" tool. These slivers are merged into the neighboring features using Esri's "Eliminate" tool.Polygons that are less than 5,000 sq. ft. and not part of a DOR city (CITY_NM = Null) were also merged via the "Eliminate" tool. (many very small slivers were manually found yet mathematically did not meet the thinness ratio threshold)The final 8 polygons less than 25 sq. ft. were manually deleted (also slivers but were not lined up against another feature and missed by the "Eliminate" tool runs)Dissolved all features back to multipart using all fieldsAll UGAs polygons remaining are unincorporated areas beyond the city limits. Any polygon with CITY_NM populated originated from the DOR "City Boundaries" layer. The DOR's City Boundaries are updated quarterly by DOR. For the purposes of this UGA layer, the city boundaries was downloaded one time (4/24/2025) and will not be updated quarterly. Therefore, if precise city limits are required by any user of UGA boundaries, please refer to the city boundaries layer and conduct any geoprocessing needed. The DOR's "City Boundaries" layer is available here:https://www.arcgis.com/home/item.html?id=69fcb668dc8d49ea8010b6e33e42a13aData is updated in conjunction with the annual statewide parcel layer update. Latest update completed April 2025.

Emergency Response Boundaries have been extracted from the WA (Enhanced) E911 system. They represent the response boundaries of emergency service providers across Washington State. Includes individual layers for Emergency Medical Services (EMS), Fire Services (Fire), and Law Enforcement Services (Law).

In response to the impacts of COVID-19, Drive-In WiFi Hotspots provide free temporary, emergency internet access for Washingtonians who do not have broadband service to their homes.

Access is available to all residents with specific emphasis on remote learning for students. Additionally, this service can be used for job searches, telehealth, telework, unemployment filing, and census participation.

The locations listed on this map represent new Drive-In WiFi Hotspot sites located at Washington State University Extension locations, as well as new and existing Washington State Library Drive-In WiFi Hotspots.

Launching primarily as parking lot hotspots in response to the COVID-19 pandemic, the free community Wi-Fi is accessible regardless of how users arrive at the locations. Some sites also offer indoor public access during business hours. Everyone using the sites – outside or inside – must practice social distancing and hygiene precautions, including staying in your vehicle or at least six feet from other users and wearing a mask if necessary.

Each hotspot will have its own security protocol. Some will be open and others will have Children’s Internet Protection Act (CIPA) safe security installed.

Broadband equity is not just a rural challenge. The drive-In Wi-Fi hotspot project addresses underserved and economically disadvantaged communities in urban and suburban areas as well.
