New lidar data
The Washington Geological Survey (WGS) has just released new lidar data for several areas in Washington. Since 2016 we have been involved in collecting over 6,400 square miles of lidar and have added many additional lidar datasets from our partners for public use. Lidar is a technology that uses light pulses to collect elevation information.
The main purpose of our new lidar collection is to map landslides for local governments to use in decision-making, as well as to replace low-quality data areas with higher quality data. This lidar will be also be used for a whole host of other mapping applications, including natural hazards, forest growth and health, river habitat and restoration, and urban infrastructure.
The new lidar covers portions of Clark, Cowlitz, Grays Harbor, Lewis, Skagit, Snohomish, Thurston, Wahkiakum, and Whatcom counties. A separate dataset was collected in partnership with King County and several city and local governments.
WGS is also working on several future lidar projects in partnership with federal agencies and local governments. These projects will include portions of Clallam, Columbia, Garfield, Grays Harbor, Jefferson, Kitsap, Mason, Pacific, Wahkiakum, Walla Walla, and Yakima counties.
You can view and download the data on our Lidar Portal.

WGS has also released 20 new lidar screensavers of the state’s diverse landscapes. The screensavers use a variety of lidar data formats (including point clouds) to display intriguing views Washington’s landforms. These images include volcanoes, landslides, faults, and river channels.
