Transitioning to our new GIS Open Data services
As part of the GIS Center’s on-going data modernization efforts, we launched our renewed GIS Open Data site at the beginning of 2026.
It’s got a fresh new look that matches the style of kingcounty.gov and it’s been simplified to help you find and use our data as quickly as possible. Additionally, the hosted Feature Services that provide the data are now hosted in ArcGIS Online instead of our on-prem ArcGIS Server. This allows us to provide you with the performance, availability, and reliability you’ve come to expect from ESRI’s map, app, and data services. Read more.
