Title: Time-series of dome and glacier growth at Mount St. Helens, Washington, 2004-2012
The video shows time-lapse changes in the lava dome and Crater Glacier from 2004-2012. The images were created from 1:12,000 scale vertical aerial photographs combined with ground control points from campaign GPS and targets. Photogrammetry software was used to collect a 3-D point cloud and combined to make a digital elevation model (DEM). Information regarding volume and rates of growth of the lava dome and glacier are extracted from DEMs to monitor surface changes in the crater.
