Project History
1996/1997 2 county Pilot Program conducted by
the Comptroller of the Treasury Maintain Parcel
maps for 80 of 95 counties Maintain Assessment
Database for 90 of 95 counties 1998 Pilot
Program extended to 3 additional
counties Program coordination transferred to
Office for Information Resources

TN Base Mapping Program Collaboration

• Funding Model
• Benefits of collaboration
• Cost Share between State, County, Municipal, and
  Federal governments
• Local Shares 25 per county
• State/Federal 75 (the rest!)

13
TN Base Mapping Program Collaboration

• Reduced costs for collection, update, and
  maintenance at startup
• Reducing redundancy of collection
• Higher accuracy data for all users
• Increased ability to integrate data
• Horizontal Integration EPA and USGS
• Vertical Integration Local govt / Census

TN Base Mapping Program - Next Steps

• Street centerlines - Intelligent layer
• Current spatially accurate
• No attribute data (dumb data !!)
• How to make it useable
• TN Department of Safety - THP dispatch system
• State E911 Board
• TN Base Mapping Program

24
TN Base Mapping Program - Next Steps

• State ECB Board (E911 Board)
• Assist and coordinate Emergency Response systems
  in a wireless world
• FCC mandate for cellular carriers to provide
  dispatchers with geographic location
• Requires uniform, consistent mapping across
  jurisdiction boundaries

25
TN Base Mapping Program - Next Steps

• State ECB Board (E911 Board)
• FCC mandate for cellular carriers to provide
  dispatchers with geographic location

• Original Implementation Date 12/31/01
• Extended to 12/31/03 (FCC Waivers)
• Currently rolling out/testing

• TNBMP Completion
• Originally 5 years, starting in Feb. 2000
• Extended to 8 years or more

• State ECB Board (E911 Board)
• Assist and coordinate Emergency Response systems

• FCC mandate for cellular carriers to provide

• Requires uniform, consistent mapping across
  jurisdiction boundaries

27
TN Base Mapping Program - Next Steps

• Intelligent street centerlines ISSUES
• Source of geography (TN BMP)
• Source of intelligence attributes
• Public source vs. Proprietary source
• Some combination of Public/Private
• Conflation (transferring the Intelligence to the
  Geography)

31
TN Base Mapping Program - Next Steps

• Intelligent street centerlines ISSUES
• Maintenance and update
• Who has authority to
• Add a street ?
• Assign an address ?
• Notify secondary and tertiary parties ?
• How are updates disseminated to required parties?

32
TN Base Mapping Program - Next Steps

• State ECB Board Wireless Phase II Mapping
  Minimum 911 Software Data Requirements
  February 1, 2002
• Software functionality, must display and use
  TNBMP data
• Minimum layers defined
• Cost recovery requirements
• Suggested deployment (GDT data via the community
  update program, then TNBMP)

33
TN Base Mapping Program - Next Steps

• State ECB Board Wireless Phase II Mapping
  Minimum 911 Software Data Requirements
  February 1, 2002
• Minimum Layers defined
• Street centerlines with complete address
  attributes
• Point landmarks churches, schools, hospitals,
  cemeteries, government bldgs.
• Area landmarks parks, airports, military bases
• Fire Hydrants and Stations
• Water features
• Administrative boundaries city, county, state
• ESN boundaries
• Digital Ortho photos

34
TN Base Mapping Program - Next Steps

• TNBMP/ECB Partnership ISSUES
• Timing (long term TNBMP project versus immediate
  need of the ECB)
• Data integrity (or lack thereof for the TNBMP)
• Spatial consistency (across jurisdictional
  boundaries)
• Maintenance/Updates (ie Custodial
  Responsibilities)

35
TN Base Mapping Program - Next Steps

• TNBMP/ECB Partnership
• Formalized by vote of the ECB January 15, 2003
• OIR/GIS Services to facilitate and manage the
  task of creating uniform, consistent Street
  Centerlines, concurrent with TNBMP Production
  efforts
• Phase 1 acquire statewide license (State,
  County, Municipal agencies) to GDTs Dynamap,
  covering the entire State, plus one county buffer
  outside the State
• OIR/GIS Services to disseminate to local
  districts
• Phase 2 transfer intelligence to TNBMP
  centerlines, for counties complete, then
  concurrently with future production
• OIR/GIS Services to disseminate to local
  districts either centerlines, or the entire
  TNBMP data set, should there be full local
  participation

36
TN Base Mapping Program - Next Steps

• How ..
• Access and disseminate
• To agencies
• To public
• For free (?)
• For fee (?) (premium services)
