Title: TNM Pilot Projects


1
The National Map
Progress and Plans
U.S. Department of the Interior U.S. Geological
Survey
2
National Spatial Data Infrastructure (NSDI)
NSDI is The technologies, policies, and people
necessary to promote sharing of geospatial data
throughout all levels of government, the private
and non-profit sectors, and the academic
community
3
National Spatial Data Infrastructure (NSDI)
Executive Order 12906
  • Reduce duplication of effort among agencies
  • Improve quality and reduce costs related to
    geographic information
  • Make geographic data more accessible to the
    public
  • Increase the benefits of using available data
  • Establish partnerships across sectors
  • The Federal Geographic Data Committee (FGDC) is
    the coordination body for developing the NSDI

4
The Need for the National Map
Federal Geographic Data Committee Webpage Much
has been accomplished in recent years to further
the implementation of the NSDI, but there is
still much to be done to achieve the vision of
current and accurate geographic data being
readily available across the country.
Data sets often
  • Are in different formats and projections
  • Do not align with one another over an area
  • Do not match across jurisdictional boundaries
  • Are not up-to-date

5
The National Map Initiative
  • Ensure the data are current
  • Make the data easily accessible online
  • Target date is 2010

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

7
The National Map Data Characteristics
  • Seamless
  • Consistently classified
  • Variable resolution, completeness
  • Consistency and integration among themes of data
  • Current to within seven days
  • Metadata
  • Available online 24-7

8
The National Map Depends on Partnerships
How will we achieve this goal?
  • In collaboration with other governmental
    agencies, academia, the private sector, and
    volunteer groups, use the best available data
  • The USGS will serve as the coordinator,
    integrator, and, where needed, producer of core
    geographic framework data responsible for
    awareness, availability, and utility

9
The National Map Strategy
  • The initial strategy is to begin with
    proof-of-concept pilot projects to address
    technical and partnership questions in
    manageable, achievable phases
  • The pilots are the foundation upon which future
    partnerships for data sharing and maintenance
    will be built
  • Pilots will show results by October, 2002

25
National Hydrography Dataset (NHD)
Lake Tahoe Area Hydrography
  • National dataset describing surface water
    features
  • NHD is based on geometry of USGS Digital Line
    Graphs (DLGs) integrated with attributes from the
    Environmental Protection Agency Reach File
    Version 3 (RF3)
  • Reach codes are unique identifiers for each
    stream segment
  • Attributes include flow direction and names
  • Based on 1100,000-scale data but designed to
    integrate and encourage the development of higher
    resolution data
  • Data are seamless across watersheds

Lake Tahoe Area Lessons Learned
Transportation Example
  • Data ingested in varying formats from four
    counties, Nevada Dept. of Transportation,
    Caltrans, Forest Service, USGS
  • Data quality varied greatly, even within datasets
  • Overlapping data had to make choices about
    which source to use where
  • Gaps in coverage filled in with USGS Digital
    Line Graph and Forest Service Cartographic
    Feature File data

37
Lake Tahoe Area Lessons Learned
Transportation Example Conclusions
  • Without consistent data models, integration is a
    lot of work
  • If we continue in the same vein, maintenance will
    take a similar amount of work
  • If maintenance takes that much work, we wont get
    The National Map built any time soon
