Topics Smoky Mtns. LiDAR (ARRA) OSM LiDAR NGA Urban-area LiDAR National Enhanced Elevation Assesment
3
Smoky Mtns. LiDAR (ARRA) 2010 ARRA grant to Univ. of Ga. Imagery and LiDAR over Tn. portion of GSMNP including Great Smokies Parkway PhotoScience (PSI) is prime contractor Spring 2010 flights hampered by snow cover and flooding: partial collect Complete collection in Spring 2011 (by end of March) Ground truthing and surveys done by UGA/PSI in Feb. & March
5
Office of Surface Mining Imagery & LiDAR Spring 2011 300 square miles NW of Knoxville Imagery: 0.3m/1 ft. color, leaf-off, 4-band. LiDAR: 1.0 PPSM, 12.5cm vert., V.13 USGS specs. Woolpert is prime contractor
7
NGA Urban-area LiDAR Chattanooga City has contract for 2011, NGA specs added USGS/NGA funds to City via Assistance Award Knoxville Collected in 2010 NGA currently evaluating existing data If accepted, may offer buy-in Memphis Scheduled for Fall 2011 collect. Currently NGA AOI only (about 1/3 of Shelby). Still time for local participation to expand collect.
8
NGA Urban-area LiDAR: Nashville
9
NGA Urban-area LiDAR (Nashville) Contract through USGS/GPSC Funds from NGA, Nashville/Davidson, USGS NGP USGS Support for Harpeth R. modeling 3 separate project requirements from same base data. NGA area includes feature extraction Nashville/Davidson area needs hydro-enforcement USGS area to base-specs only (hydro flattening) NGA funding delayed to late March due to Federal budget (CR) Nashville requires spring collect, but NGA funds not available in time USGS/NGP adding additional funds to cover NGA area Collection in March w/out NGA funds

National Enhanced Elevation Assessment Date, 11/4/2010 Keith W. McFadden USGS, Geospatial Liaison for Georgia and Tennessee
11
National Enhanced Elevation Assessment Business Uses and Benefits Quantify answers to key questions: Is it more cost effective for the Government to manage the collection, processing and distribution of enhanced elevation data within the context of a national program? Are there additional national or agency benefits derived from such a strategy? What does the optimized program look like? 11
12
National Enhanced Elevation Assessment About the Project Team Sponsor: National Digital Elevation Program (NDEP) committee member agencies Funding Partners: U.S. Geological Survey (Managing Partner) National Geospatial-Intelligence Agency Federal Emergency Management Agency Natural Resources Conservation Service In-kind Partners: National Oceanic and Atmospheric Administration Many Federal agencies, state agencies and other study participants Contractor: Dewberry 12

14
National Elevation Dataset 14 80 percent of elevation data is more than 30 years old and will not meet accuracy requirements for many applications.
15
High Resolution Elevation Data 15 The United States has high resolution elevation data available for abut 20 percent if the country.
16
Technology of Choice - LiDAR Laser Pulse and Returns GPS Point Cloud 16 Light detection and ranging (LiDAR) System with a laser and detector (range), scanning mirror (laser direction), GPS (location), and IMU (orientation) Output 300,000+ laser pulses per second Record laser reflection information Billions of recorded points create 3- dimensional representation of bare earth, vegetation and structures at centimeter- level accuracy Many forms of “elevation” can be derived

National Enhanced Elevation Program Strategic Goals Directed, national approach to meet critical business uses for precision elevation data Standardized quality products collected once and meeting multiple Federal and State mission needs Consistent measurements across projects for reliable science Readily accessible data in useful formats Use of leading edge technology Balancing requirements, benefits and costs 22
23
National Enhanced Elevation Assessment A highly distributed program where each agency independently plans, collects, manages, and distributes their data – a status quo solution. This solution anticipates that agencies would coordinate their activities with others to the extent that they do so today. A national program where enhanced elevation data acquisition, processing, and distribution responsibilities are shared and well coordinated by Federal, State, and other partners. A national program where the Federal Government administers the enhanced elevation data acquisition, processing and distribution on behalf of all users through a lead Federal Agency. Possible Program Implementation Scenarios 23
24
National Enhanced Elevation Assesment Idealized Schedule FY10 Establish project team and management oversight Initiate National Enhanced Elevation Assessment (NEEA) Build on ARRA success and partnerships with FEMA, NGA, states and others FY11 National Enhanced Elevation Assessment complete Develop Implementation Plan FY12 Develop supporting documents – alternatives analysis, design, implementation plan, etc. Develop organizational approaches FY13 Implementation begins 24
25
Status: On-going. Currently conducting internal (USGS) & Other Fed agency needs assessments. Development of business cases Cost/benefit analysis Determine areal and functional dependencies Next step: State/local user input Interviews and surveys of key stakeholders National Enhanced Elevation Assesment
