Remote sensing and image interpretation

---

The front cover a topographic image derived for airborne lidar data, two days affer the massive Oso landslide (March 2014, in Washington State). With more than forty deaths and nearly fiffy homes destroyed, this event ranks among the deadliest kandslides in U.S. history. Lidar (light detection and ranging, Chapter 6) is an active remote sensing technique that ivolves transmitting pulses of laser light toward the ground and measuring the elapsed time of pulse retums. The laser’s rapid pulse rate yields a dense cloud of points that can be analyzed to extract the shape of thr ground surface, as well as trees, structures, and other objects. Analysis of lidar images from before and after the event shows that the landslide covered an area of approximately 120 hectares (300 acres) and that about four million cublic meters (5.2 million cubic yards) of material moved downslope. Chapter 8, Section 8.14 (Natural Disaster Assessment) provides additional imagery and discussion of the Oso landslide.
