AB: LiDAR acquisition is a key component of the GeoEarthScope Initiative. LiDAR provides data with a broad range of applicability to many of the EarthScope goals. A working group was convened to identify primary targets for data acquisition, rank these targets, and propose a data acquisition scheme to effectively acquire these data within the GeoEarthScope funding time frame. The Regional Targets are: a.) Northern California – including the San Andreas Fault north of Parkfield, and other major strands of the San Andreas Fault system; b.) Southern California – including the Garlock Fault, Eastern California Shear zone south of the Garlock, and the Elsinore Fault; c.) Eastern California, Walker Lane, and Basin and Range fault systems – including faults of the Eastern California Shear Zone north of the Garlock Fault; d.) Intermountain Seismic Belt – including the Wasatch Fault, Teton Fault, and Yellowstone Park area; e.) Alaska – including the Castle Mountain and Denali Faults; f.) Cascadia – including the Little Salmon fault zone in southern Cascadia, the Calawah Fault in the Washington forearc, and imagery in the Yakima Fold belt termination. The Working Group recognized that available funding would likely preclude obtaining data from all high priority sites The Working Group wrestled with several important issues that affect the data acquisition plan and the prioritization of sites. The WG tried to develop a plan that honored the primary EarthScope goals, recognizing the limited funding available. In particular, in order to maximize the coverage obtained and serve the broadest community, the WG elected to utilize relatively narrow swath widths (typically 1 km, widened to 2+km in key regions), which allowed more line-kilometers of data to be obtained. The unavoidable consequences of this choice are that areas away from the main fault strands will be unsampled. Data acquisition is underway. The Northern California acquisition (supplemented by financial support from state and federal agencies such as the PUC and USGS) was completed in April 2007, with processed data available through UNAVCO data management tools (including the GEON LiDAR workflow project). Additional data acquisition for the remaining targets is ongoing with all data acquisition to be completed by September 2008.
