Fall AGU Special Session on Ground Based Geodetic Techniques and Science Applications

Session announcements for the fall American Geophysical Union (AGU) meeting in San Francisco are beginning to appear. The following session on ground based geodetic techniques includes an emphasis on terrestrial laser scanning:
Dear Colleagues: We would like to bring to your attention the following special session on Ground Based Geodetic Techniques and Science Applications to be held at the 2010 Fall AGU Meeting in San Francisco, December 13 - 17:

LiDAR Beginning to Appear in Google Maps Terrain Layer

One of my favorite features in Google Maps is the terrain layer, which provides a shaded relief (aka hillshade) view of the topography derived from a digital elevation model. Google has done a nice job generating a visually pleasing terrain layer, and we use it for all of our Google Maps-based interfaces in OpenTopography. Google appears to use a range of digital elevation model data sources to derive the terrain layer.

OpenTopography Overview Video

The OpenTopography ASU Capstone team - a group of senior undergraduate (who have now graduated - congrats!) School of Computing and Informatics students at Arizona State supervised by OpenTopography Co-I Ramon Arrowsmith - have released another nice video about OpenTopography. This video provides an introduction to the OpenTopography Facility:
