  5. The National MapBackground • 55,000 maps / 33,000,000 hours / $1.6 billion • Valuable part of economy and infrastructure • Value is eroding due to age

  6. The National Map Distributed set of consistent, integrated, continually maintained, basic spatial data for the United States. Serve as the Nation's topographic map for the 21st century.

  7. The National Map: Data Themes • Orthorectified imagery • Land cover • Elevation • Transportation (road, rail, other) • Hydrography • Structures • Boundaries (political & admin) • Geographic names

  8. The National Map: Characteristics (1) • Seamless not quad based • Current to days or weeks, not years • Basic spatial data • Foundation for additional data stable feature identifiers as Velcro reach codes, addresses, linear referencing

  9. The National MapCharacteristics (2) • Digital data and paper maps • GIS ready • User friendly • Online access, web accessible, 24-7 • Accurate, best available • Public domain, but link to other data • Standardized, consistent, modern datums

  10. The National Map: Characteristics (3) • Integrated themes • Continually maintained • Transactional updates • Feature metadata • Roll back to versions for any point in time • Based on partnerships • Fed by state & local data and knowledge • National coverage • Variable resolution

  11. The National Map:Blankets and Quilts • Blanket • Consistent • Seamless • Implementation can be more “rich” (aka complicated) • Slower to occur (integration takes time) • Quilt • Less consistent • Has seams • Implementation currently simple • Updates can occur more quickly (less or little integration) • More choices of data

  12. Geospatial Web ServicesOpen Geospatial Consortium • OGC interface specifications • Web map service – returns a picture • Web feature service – returns geometry, attributes, and relationships • Web coverage service – returns raster-model data

  13. National Hydrography Dataset (NHD) • Combine best of EPA RF3 and USGS DLG • 100K first • 24K now • Many partners • Geodatabase model

  14. National Elevation Dataset (NED) Elevation data for • Mapping • Classifying land cover • Producing orthoimagery • Modeling hydrologic and wildland fire processes

  15. National Elevation Dataset (NED) Elevation data for • Mapping • Classifying land cover • Producing orthoimagery • Modeling hydrologic and wildland fire processes

  16. National Land Cover Dataset (NLCD) NLCD 2001 will be part of a land characterization database that also includes: • LANDSAT 7 imagery • Terrain slope, aspect, and elevation • Soil moisture • NLCD 1992 • Surface impervious and tree cover • Classification rules

  17. Coordination& Standards Consistent & Current Content Data Discovery & Access The National Geospatial Program Office • Coordination, standards, policy – Federal Geographic Data Committee • Discovery and access – Geospatial One Stop • Integrated base data – The National Map

  18. National Geospatial Programs Office • A Unified Approach to the NSDI • Align USGS national geospatial activities and responsibilities • Federal Geographic Data Committee • Geospatial One Stop • National Map • National Atlas • Reaffirm the direction of individual activities • Expand partnership offices • Assess USGS geospatial products and services

  19. Disciplines of the U.S. Geological Survey • Geology (GD) • Water Resources (WRD) • Biological Resources (BRD) • Geography • GIO, includes NGPO
