Information and discussion related to high-resolution lidar topography for the Earth sciences
The USGS has released a beautiful poster of Mount St. Helens created from high-resolution LiDAR topography data. The poster is USGS General Information Product 116 and is freely available for download in PDF format at either 17x22 inches or 32x42 inches.
Via Paolo Tarolli, an announcement about a session at this year's European Geoscience Union Meeting in Vienna. The session emphasizes analysis techniques for high-resolution digital elevation models (DEMs) of Earth, seafloor or planetary landscapes:
A NOAA expedition that concluded this past Sunday focused on mapping the offshore extent of the San Andreas fault at high-resolution. Using sonar mapping and other imaging and geophysical technologies, the NOAA-funded group, led by Chris Goldfinger from Oregon State University, is building a 3D model of the fault that they hope will reveal information about earthquake behavior as well as the role of the fault in undersea life:
The International Society for Photogrammetry and Remote Sensing (ISPRS) Working Group V6 is promoting a session at the April, 2011 Association of American Geographers (AAG) annual meeting in Seattle on "
