Detailed Description

Image of Mount St. Helens lava domes and Crater Glacier on October 1, 2012. The image was 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 this digital elevation model (DEM) focusing on the volcano's crater.
