Today, Ionut Iordache announced the release of NCALM's new Google Earth-based LiDAR Data Distribution Center. This new system is much improved over NCALM's former means of distributing their public datasets and is likely to be very popular and successful. Via a simple KML file downloaded from the DDC webpage, users can access footprints showing the extent of all datasets currently available, metadata, links to download standard digital elevation model products, and hillshade overlays that can be viewed directly in Google Earth.
I am currently working with Ionut to provide an overview of... more

Today at 10 am The Great Southern California ShakeOut staged an Mw=7.8 earthquake on the southern San Andreas Fault to raise public awareness of earthquake hazards and to allow public responders and the scientific community to practice their response to such an event. As part of the scientific response, UNAVCO is coordinating community equipment deployment and data acquisition activities via their Great Southern California ShakeOut Response discussion forum. A sub-forum, coordinated by David Phillips, is tracking the airborne and terrestrial LiDAR response to the earthquake. As of 12:23 pm... more

The National Center for Airborne Laser Mapping has issued their annual call for Seed Proposals from graduate students.
The National Center for Airborne Laser Mapping (NCALM) invites graduate students who are interested in research grade ALSM data to make use of the center's facilities through the Seed Money Projects programme. This year the program will fund 10 seed projects covering area no more than 40 sq. km. each.The motivation for such seed projects is to have graduate students start their preliminary scientific research and subsequently develop larger NSF proposals to make... more

Ramon Arrowsmith points out that CGIAR-CSI has released a new version (v.4) of their 90m SRTM Digital Elevation Data.
The SRTM data now available from this site has been upgraded to version 4. This latest version represents a significant improvement from previous versions, using new interpolation algorithms and better auxiliary dems. We are confident this is now the highest quality SRTM dataset available.
