Information and discussion related to high-resolution lidar topography for the Earth sciences
A common question we receive at OpenTopography is "do you know if there is lidar available for location xxx?". Typically, when we get this question I refer people to the OpenTopography Find Data page (an increasingly rich source for lidar data) and this page of links to online sources of lidar. But, there are large amounts of data collected by federal, state, and local agencies that can be hard to track down.
The National Center for Airborne Laser Mapping (NCALM) has announced their 2012 call for Graduate Student Seed Proposals. The NCALM Seed program provides an excellent opportunity for graduate students to obtain lidar data for their research. Data collections are limited to 40 square kilometers.
The National Center for Airborne Laser Mapping (NCALM) has a project scheduled for January 2013 in Hawaii, and is looking for other potential partners who may also be interested in having data collected while they are there. This is a good opportunity to take advantage of the fact that the NCALM instrumentation will already be in Hawaii. Details:

Yet another AGU 2012 session on lidar, high-resolution topography, and change detection that could be of interest to the OpenTopography community:
EP023: Quantifying Hillslope and Fluvial Processes Through Change Detection Using High-Resolution, Multi-Temporal Topographic Data
Representatives from NCALM, UNAVCO and OpenTopography are organizing the following session at the 2012 American Geophysical Union (AGU) in San Francisco, December 3-7, 2012. The abstract deadline is August 8th.
It is 2012 American Geophysical Union (AGU) session announcement season. This is a session convened by several OpenTopography collaborators that will be of great interest to the OpenTopography community:
We invite you to join us at the 2012 AGU Fall Meeting for a session titled "4-D Lidar: changes to Earth's surface measured from differencing repeat dense topographic datasets."
A pair of recent publications related to paleoseismic research in California feature lidar topography data accessed and processed via OpenTopography. Both papers utilize B4 lidar data extensively, and OpenTopography played an integral role in providing access to both the point cloud and custom digital elevation models discussed in the publications.
At last month's UNAVCO Science Workshop they introduced an evening of Ignite talks presented by members of the UNAVCO community. The event was well attended and quite fun. The full set of videos are now available here: http://igniteshow.com/events/2012-unavco-science-workshop
