“A New Beginning”

tnbmp a new beginning
TNBMP…A New Beginning
  • Initial Production Complete
  • Accomplishments Summary
  • Ortho Imagery Pilot Program
  • TDOT Partnership
  • Enterprise GIS – TNMap

TNBMP…A New Beginning

Let’s take a look back…

TN Base Mapping Program

Pilot Counties – 1997, 1998

milestones accomplishments a few quick facts
Milestones/AccomplishmentsA few quick facts:
  • Total cost: $28 million
    • $19 million (ortho, DTM, planimetrics)
    • $ 9 million (parcels)
  • Collaboration/Local partnerships
    • $5 million in contracts
    • 250+ organizations in 57 counties
    • Leveraged existing data in 6 counties
    • Local GIS maintenance in 45 counties
sustainable ortho imagery principles
Sustainable Ortho Imagery Principles
  • Cost effective approach that meets needs of State and local users
  • Leverage federal funding to help reduce or eliminate duplication of effort
  • Regional or Statewide acquisition
    • County by county more expensive/inefficient
    • Eliminate production of overlapping map sheets
  • Develop set schedule for updates
  • Examine State/local cost share
data maintenance strategies
Data Maintenance Strategies
  • Initial statewide production complete
  • Ortho Imagery is 7 years old in some counties
  • Population growth/development driving demand for new imagery
  • Need a plan for ortho imagery update/maintenance
data maintenance strategies1
Data Maintenance Strategies
  • FY07 - 08 Funding in place
  • Extended current contract from 10/07 to 10/08 and modified specs to emulate “Imagery for the Nation” and local requirements
  • Identify counties with significant growth, imagery that is outdated, TDOT region 1 (upper East TN)
  • Continue operating under current cost share model (75% State / 25% local)
dept of transportation
Dept. of Transportation
  • Existing analog aerial photography program
    • Large scale engineering projects (site specific)
    • Right-of-way corridor studies
    • Regional planning efforts
  • Need to develop or enhance internal processes for using new technology
  • Identified need to update current photogrammetry processes
  • Completed “Gap” analysis to provide detailed recommendations
oir gis tdot partnership
OIR-GIS/TDOT - Partnership
  • TDOT Modernizing Equipment
    • Digital camera suitable for ortho photo production
    • Training staff on new photogrammetry production req.
    • ortho acquisition for ¼ of State annually
  • OIR-GISresponsiblefordata hosting and distribution
    • TNMap enterprise GIS
    • Dissemination to local government
  • 2008 Acquisition: Region 4 (West TN)

sustainable ortho imagery principles1
Sustainable Ortho Imagery Principles
  • Cost effective approach that meets needs of State and local users
  • Leverage federal funding to help reduce or eliminate duplication of effort
  • Regional or Statewide acquisition
    • County by county more expensive/inefficient
    • Eliminate production of overlapping map sheets
  • Develop set schedule for updates
    • 4 year cycle
  • Revisit State/local cost share
slide25
Enterprise GIS Development
  • How can State agencies create and maintain spatial data once and use (share) it many times?
  • The “Tennessee Map” (TNMap)
the tennessee map tnmap enterprise gis architecture
The Tennessee Map (TNMap): Enterprise GIS Architecture
  • Goals
    • Develop enterprise GIS infrastructure to provide secure, usable, and easy access to TNBMP data
    • Provide State agencies with ability to publish data to enterprise GIS
    • Support vision of USGS’ National Map and NSDI
    • Identify data stewards, reduce or eliminate redundant GIS data collection

The Tennessee Map (TNMap): Enterprise GIS Architecture
  • Initiatives/Strategies
    • Staffing requirements (2 to 8)
    • Enterprise Geospatial Data Repository
    • GIS Data Inventory and Data Stewardship
    • TN Geospatial Data Sharing Standards
    • Enterprise Services and Geospatial Applications
    • Geospatial Standards (software, metadata)
business case for enterprise gis
Business Case for Enterprise GIS

The Tennessee Map (TNMap): Enterprise GIS Architecture

  • Comptroller – Manage real property
  • TWRA/TDEC/Ag. – Governor’s Heritage Conservation Trust Fund
  • TDOT – Right-of-way acquisition
  • ECD – community planning, land use regulations, business development

ROI: Create once – use many times, eliminates duplication of effort, saves time and money

TNMap…More than just a map

  • Geo-portal application
  • Base Map Data Repository
  • Shared GIS infrastructure for application hosting
  • Access: Public, State GIS users

TNMap portal demonstration…

slide31
TNBMP…A New Beginning
  • State will provide local government with updated ortho imagery – 4 year cycle
  • Local gov. will provide the State with updated parcels, street centerline GIS data
  • Counties with new imagery (2007 or 2008):
    • Local cost share is 25% of parcels only
slide32
TNBMP…A New Beginning
  • Vision: Maintain a statewide GIS base map through partnership development that can be used in support of a wide range of local, state, and federal programs
