More new lidar images of Washington’s landforms!
The Washington Geological Survey has just added 10 new lidar-derived images of the State’s landforms to our image collection. This new set includes landscapes shaped by glaciers, ice-age floods, rivers, and landslides. For more information, check out the image descriptions below and use the associated links to view and download high-resolution versions of each one. […]
New map poster offers a bird’s-eye view of Mount St. Helens
In recognition of Volcano Awareness Month in Washington State, the Washington Geological Survey (WGS), with support from the U. S. Geological Survey (USGS), has released a new map poster: ‘Mount St. Helens: A Mountain Reborn’. The map features a bird’s-eye view of the volcano that famously erupted on May 18, 1980. That eruption instantly transformed […]
Celebrate GIS Day with new lidar images of Washington’s geologic landforms!
In celebration of GIS Day 2021, the Washington Geological Survey is releasing ten new lidar images featuring geologic landforms from around the State.
High-resolution lidar images of Washington’s geology now freely available
The Washington Geological Survey (WGS) has released 50 high-resolution lidar-derived images of the State’s geology and geomorphology through the Washington State DNR’s Flickr page. The images are available in 16:9 format (7,200 x 4,050 pixels) and 4:3 format (7,200 x 5,400 pixels). Ten of the images are new (see below) and 40 of them were […]
New Washington lidar data and screensaver images!
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 […]
New Lidar Story Map for GIS Day!
To celebrate GIS Day, the Washington Geological Survey has released a new story map titled: The Bare Earth—How lidar in Washington state exposes geology and natural hazards. Geologists in Washington State use lidar to map landslides and faults, to study volcanoes, glaciers and rivers, and to model tsunami inundation. This narrative features over 50 intriguing […]
New Poster—Folds and Fossils of the Chuckanut Formation
A new map poster is available titled Folds and Fossils of the Chuckanut Formation in Northwestern Washington.
Lidar Imagery Now Available for Viewing on the Washington Geologic Information Portal
It’s finally here! You can now view lidar imagery in our Geology Portal. We’ve added mosaics of both bare-earth and top surface lidar hillshades to the list of available base layers. What’s a Lidar Hillshade? Lidar hillshades are renderings of the lidar elevation model using simulated illumination. Bare-earth lidar shows only the ground surface (trees, vegetation, […]
Statewide Protocol for Landslide Mapping from Lidar Data Released
The Washington Geological Survey is pleased to announce a new publication that explains the detailed protocol that Survey geologists are using to systematically map landslides using lidar. This protocol closely follows the methods used by Oregon Department of Geology and Mineral Industries to map landslides in Oregon. The objective of the protocol is to establish standardized methods for […]
