Portland LIDAR Survey
A $1-million project to map the terrain of Portland, Oregon will take place over the next few weeks, the Oregonian reports. The aerial LIDAR survey is intended to create a hyper-accurate terrain map that will be particularly useful in predicting areas at risk of landslides, to which Portland is particularly prone.
Identifying landslides is only one of the uses for the new lidar images. Madin also is searching for any signs on the surface of the Portland Hills Fault and other faults. Other agencies are using the data to update flood plain maps, plan roads and highways, and for stream-restoration projects.
Previous LIDAR-based mapping of Portland is available at Oregon Geology’s Pilot LIDAR Project site. Thanks to Lon Lasher for the link.
