    3. The Challenge of Community LiDAR data cont. National LiDAR Initiative Rough calculation using a NASA high elevation acquisition approach: Land area of US = 9,161,923 sq km Assuming: 2 laser pulses per sq meter an average of 1.5 returns per pulse 35 data bytes per return = 1 x 10 15 bytes of point cloud data = 1 petabyte (1,000 terabytes)

    5. The Vision: Utilize cyberinfrastructure developed by GEON to offer online data distribution, DEM generation, and analysis of large LiDAR datasets. Completely internet-based workflow: Point cloud to visualization Utilize modular web services to complete a variety of processing and analysis tasks. Offer users control of processing and analysis parameters.

    7. Current GLW Status Datasets online: Northern San Andreas Fault West Rainier Seismic Zone E. California Shear Zone (Mike Oskin, UNC, PI) 4. Full B4 Dataset (Southern SAF and SJF) Total of ~6.4 billion LiDAR returns available via GLW Use Statistics ~43 billion returns processed 2103 unique jobs submitted 118 registered GLW users
