Existing Landslide Inventory Mapping
In 2005, DOGAMI began a collaborative landslide research program with the U.S.Geological Survey (USGS) Landslide Hazards Program to identify and understand landslides in Oregon. Using high-resolution Lidar mapping technology and following a strict protocol, DOGAMI set out to complete an inventory and develop maps of existing historic and prehistoric landslides throughout the state.
View the Existing Landslide Inventory map that covers the Lake Oswego area. As you move your mouse over the different quadrants, clicking on the respective quadrant will open a larger map of the area of coverage.
Additional information can be found in the DOGAMI Fact Sheet entitled Understanding Landslide Deposit Maps.
The mapping protocol used by DOGAMI to develop these maps is presented in: PROTOCOL FOR INVENTORY OF LANDSLIDE DEPOSITS FROM LIGHT DETECTION AND RANGING (LIDAR) IMAGERY, SPECIAL PAPER 42 by William J. Burns and Ian P. Madin. Copy of the report.
