Title: The National Map. Topographic Mapping for the 21st Century

The National Map Topographic Mapping for the 21st
Century

USGS Most Famous Product
  • Once-over coverage was an immense engineering
    feat
  • Cost of replication today would be over 2
    billion
  • The only national synthesis of topographic
    content that is
  • Comprehensive
  • Transjurisdictional
  • Border to border and coast to coast

3
Whats Happened to USGS Topographic Maps?
Baltimore, MD
  • Value is eroding rapidly as maps become
    increasingly outdated
  • Divergence between base data and topographic maps
  • Duplication of effort among and between
    geographic information sectors

The Value of Topographic Information
  • Input to national policy and planning decision
    making
  • Key to effective land and resource management
  • Essential for efficient delivery of government
    services
  • Critical for homeland security
  • Foundation for economic enterprise

5
The National Map Vision
  • A seamless, continually maintained, nationally
    consistent set of basic geographic data
  • Partnerships for data stewardship
  • Relink topographic maps with base geographic data
  • Underpin Federal activities, and those of other
    public and private organizations
  • Support integrating, sharing, and using spatial
    data easily and consistently

6
The National Map Data Content
  • Orthorectified imagery
  • Land cover
  • Elevation
  • Vector layers
  • Transportation
  • Hydrography
  • Structures
  • Boundaries
  • Geographic names

The National Map Operations
  • Build initial version from best available data
  • Improve throughout decade - shift to maintaining
    currentness
  • Establish partnerships for data maintenance with
  • Federal agencies
  • Tribal governments
  • State and local governments
  • Private industry
  • Local trained or certified volunteers
  • Create a networked, distributed collection of
    databases linked by the Internet
  • Obtain feedback from partners and users

10
Organization Partners Roles
  • Federal identify needs, synchronize programs
    and resources, and collaborate on data and
    standards
  • State, Regional, Tribal and Local coordinate
    consortia, identify changes and provide updates,
    and collaborate on data
  • Private Industry provide tools,
    interoperability standards, and data conduct
    research
  • Academia provide training and conduct research
  • Libraries ensure public access to The National
    Map
  • Volunteers identify changes and provide updates

National Map
14
Lessons Being (Re)Learned
  • Data must exist before, during and after an
    event, and be readily accessible
  • Partnerships are required among State, local, and
    Federal agencies, and the private sector
  • Map information is a national infrastructure,
    just like the Interstate Highway System
