  1. Moving The National Map Forward Mark Myers Director U.S. Geological Survey Alaska Surveying and Mapping Conference Anchorage, AK February 25, 2008 U.S. Department of the Interior U.S. Geological Survey

  2. Mapping – A basic function of government Thomas Hutchins appointed Geographer of the United States by the Continental Congress in 1781. Federal geographic expeditions continued through Lewis and Clark to the Great Western Surveys. Hayden Survey Pack Train on the Yellowstone River, 1871

  3. A Topographic Map for the Nation • John Wesley Powell • USGS Director, 1881-94 • Articulated the vision and began the development of a U.S. national map

  4. Powell on National Mapping • Testimony to Congress on December 5, 1884 • “A Government cannot do any scientific work of more value to the people at large, than by causing the construction of proper topographic maps of the country” Gerald FitzGerald Chief Alaskan Topographer, 1938-42 Chief Topographic Engineer, USGS, 1947-57

  5. Once-over mapping was an immense feat The only national synthesis of geography that is Comprehensive Standardized Transjurisdictional Border to border, coast to coast Cost of replication today would be $2 to $3 billion USGS Topographic Maps

  6. Seeking synergy in science Evangelical Leaders Join Global Warming Initiative - New York Times February 8, 2006 By LAURIE GOODSTEIN Despite opposition from some of their colleagues, 86 evangelical Christian leaders have decided to back a major initiative to fight global warming, saying "millions of people could die in this century Copper prices set another recordBy Dale Funk, Contributing EditorApr 1, 2006 12:00 PMWhile most wire and cable industry veterans and commodity analysts expected 2006 to be a year of moderation for copper prices, when copper jumped 9.45 cents to nearly $2.36 a pound on March 17 on the New York Mercantile Exchange, it set another record. A British experts report on climate change warns that failure to curb global warming could trigger worldwide economic devastation, with poor countries hit first and hardest.  Prime Minister Tony Blair called for urgent international action.

  7. USGS Science Strategy Directions Understanding Ecosystems and Predicting Ecosystem Change Energy and Minerals for America’s Future A National Hazards, Risk, and Resilience Assessment Program The Role of Environment and Wildlife in Human Health A Water Census of the United States Climate Variability and Change Data Integration and Beyond

  8. TheNational Map – essence A collaborative effort to improve and deliver topographic information for the nation. The goal… trusted, nationally consistent, integrated, current geospatial information available online for a broad range of uses.

  9. TheNational Map - elements • A contribution to the NSDI • Includes eight data layers: hydrography, elevation, imagery, geographic names, boundaries, transportation, land cover, structures • Provides public domain data to support • USGS topographic maps at 1:24,000-scale • Products and services at multiple scales and resolutions • Analysis, modeling and other applications at multiple scales and resolutions • Built on partnerships and standards

  10. The National Map - vision • A seamless, continuously maintained,nationally consistent set of base geographic data • Developed and maintained through partnerships • A national foundation for science, land and resource management, recreation, policy making, homeland security • Available over the Internet • The source for revised topographic maps

  11. TNM and Science - Ecosystem Mapping

  12. TNM and Science - Ecosystem Analysis

  13. Three initiatives for The National Map • Imagery for the Nation (IFTN) • LiDAR for the Nation (LFN) • National Land Imaging Program (NLIP)

  14. Imagery for the Nation (IFTN) • A vision for a sustainable and flexible digital imagery program for the nation • Would advance The National Map imagery goals much more rapidly through predictable sustained funding • IFTN goals for predictable coverage and standard products align with the goals of TNM • The USGS supports IFTN, recognizes the challenges of imagery acquisition in Alaska • USGS POC – George Lee, 650-329-4255,

  15. LIDAR for the Nation Initiative A complete, consistent, current, high res LIDAR dataset would have great value for multiple stakeholders in many applications. Program would involve partners from local, state, fed agencies; private sector, academia. Acquired data in public domain (no licensing restrictions) USGS CLICK website provides information for LiDAR community USGS POC – Greg Snyder, 703-648-5169,

  16. LiDAR point cloud - Vegetation

  17. LiDAR point cloud - Structures

  18. Plan for a National Land Imaging Program • Proposal for DOI to manage U.S. civil-operational land imaging • Endorsed by the Office of the President (OSTP) • USGS POCBruce Quirk,

  19. Future guidance for The National Map – key sources • National Research Council (NRC) report: A Research Agenda for Geographic Information Science at the United States Geological Survey • National Geospatial Advisory Committee – DOI led • Geospatial Line of Business

  20. TNM Progression:Transitions

  21. Alaska – different from the lower 48Historically lacking in hi-res geospatial data • Economy dependent on resource development • Infrastructure poor • High percentage of Federal lands • Challenges of vast, remote landscape • Resource storehouse • Permafrost warming • Increased coastal erosion • Glaciers thinning, retreating • Forest fires • Insect infestations

  22. Coastal Erosion Drew Point - 2004 Gary Clow photo (USGS) Undercutting & Collapse of Permafrost Blocks

  23. Topographic Base (1955)

  24. Landsat 5 (1985) – Band 5 (grayscale)

  25. Landsat 5 (2005) – Band 5 (grayscale)

  26. 50 Years of Coastal Erosion Note: Barrier island north of Pogik Bay not included

  27. Moving Forward for Alaska • Integrated analyses of AK issues demand more comprehensive geospatial data • Energy and mineral exploration, development • Natural resources – forests, fish, wildlife • Cultural resources • Emergency, natural hazard response • Bellwether region for global climate change USGS Alaska Science Center 907-786-7000

  28. Moving Forward Together • Improving technical, collaborative aspects of The National Map • Including Alaskan geospatial community • Improving USGS geospatial partnerships in AK • National Map Customer Research Projectinitial meeting here • Full-time USGS Geospatial Liaison • USGS to become a partnerAK Statewide Digital Mapping Initiative
