This dataset displays the aviation related businesses within Washington State. Industry sectors were selected that include businesses with a high propensity to rely on aviation services as part of their typical business activities. These activities include scheduled commercial service, general aviation, and air cargo. Industry types were identified by North American Industry Classification System (NAICS) code based on the findings of numerous economic impact studies conducted for state departments of transportation and individual airports across the U.S. and in close consultation with WSDOT Aviation. Information was collected from ESRI’s Community Analyst application in September 2019. This data is provided to the public as courtesy for general aviation planning purposes. The information provided should not be relied upon for navigational, engineering, legal or other site-specific uses. It may not show an airport's current capabilities or configuration. Inaccuracies in the layer may be attributed to: spatial errors in data, airport construction, or recent changes in airport capabilities.
