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

  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

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
