Geology Lecture: LiDAR, the "Virtual Chainsaw"
Saturday, December 16, 2017, 04:00pm - 05:00pm

Geologist Ralph Haugerud will present what you need to know about LiDAR, a tool that geologists and land managers whimsically call the “Virtual Chainsaw.” This relatively new technology enables image data to render a “Bare Earth” view, one devoid of buildings and vegetation.

Airborne LiDAR (Light Detection and Ranging) has changed earth imaging. LiDAR combines differential GPS (an inertial measurement unit) with rapid-fire scanning by a laser rangefinder to generate thousands of positions per second with high accuracy. Combined, these instruments image the shape of landscape with unparalleled precision. Ralph will discuss some examples from Washington.

This illustrated lecture will be presented to the public free of charge; an optional donation of $5 would be appreciated to defray expenses.
