  1. Update on the OpenTopography Facility Chris Crosby (SDSC @ UCSD) & Ramon Arrowsmith (ASU) Lidar2 Workshop: New Tools in Process-Based Analysis of Lidar Topographic Data June 2nd, 2010

  2. EarthScope LiDAR Project The Challenge of Community LiDAR data • LiDAR acquisition over 5600+ km2 = 50+ billion LiDAR returns! • Thousands of DEMs as “standard” products • Large user community with variable needs and levels of sophistication. How do we deliver large community data sets such as these? What tools are necessary? Full Waveform?! Northern California GeoEarthScope LiDAR

  3. Tiered Data Access: • Large and diverse user community requires range of data products. • Pretty picture for synoptic data browsing and education. • Google Earth • Vast majority of earth science users want a standard gridded product: • Optimized DEM • Most computationally and resource intensive data (point cloud) are currently the least often accessed. • Access to “raw” data to optimize terrain representation.

  4. NSF Facility: 3 year support (funding via EAR IF and OCI) • Increase the amount of Earth science-oriented LiDAR available via OpenTopography (Discussion Point #1) • Enhanced web-based processing capabilities, with a focus on computationally intensive tasks • Community support: (Discussion Point #2) • Software • Tutorials and short courses • Education and outreach materials

  5. OpenTopography as portal Community Support Cloud, waveform CSDMS

  9. Cyberinfrastructure in Action

  10. Available Data: • 60 billion LiDAR returns + thousands of 1 km2 DEM tiles available • ~7500 sq km of data • ~50 GB of hillshade imagery accessible in Google Earth. http://opentopography.org/data

  11. Logging Data Usage • Usage stats: • Help to optimize system design • Are very compelling to funding agencies and program managers

  12. Building a community of users: social networking • Blog: • News • Announcements • Processing and data analysis tips • Data sources • Forums: • Encourage discussion between users • Share knowledge, tips, tricks Social Media:

  13. Discussion #1: Community (data analysis) tool repository • Centralized and current access to community/PI developed software • Evolution of repository? • html, wiki, cvs / svn / “OTforge” • Sub-community sandbox • Community demand-driven deployment in OT production

  14. Ex: Community Surface Dynamics Modeling System (CSDMS) Wiki (http://csdms.colorado.edu/wiki/Terrestrial_Mo)

  16. Discussion #2: OpenTopography Data Priorities? • Type? • Grids? • Points? • Other sources: TLS, total station, bathy, etc. • Quality Threshold? • Research Grade • Shots/m2 • Metadata / documentation? • Domain-driven? • Data relevant to EAR research regardless of source • Low-hanging fruit?

  17. Questions & Comments:ccrosby@sdsc.edu
