OIR – GIS Services 3 Retreat 2007, 10/31/07 Let’s take a look back… TNBMP…A New Beginning

OIR – GIS Services 4 Retreat 2007, 10/31/07 Pilot Counties – 1997, 1998 TN Base Mapping Program

OIR – GIS Services 5 Retreat 2007, 10/31/07

OIR – GIS Services 6 Retreat 2007, 10/31/07 Milestones/Accomplishments A few quick facts: Collaboration/Local partnerships –$5 million in contracts –250+ organizations in 57 counties –Leveraged existing data in 6 counties –Local GIS maintenance in 45 counties Total cost: $28 million –$19 million (ortho, DTM, planimetrics) –$ 9 million (parcels)

OIR – GIS Services 7 Retreat 2007, 10/31/07

OIR – GIS Services 8 Retreat 2007, 10/31/07 Sustainable Ortho Imagery Principles Regional or Statewide acquisition –County by county more expensive/inefficient –Eliminate production of overlapping map sheets Develop set schedule for updates Cost effective approach that meets needs of State and local users Leverage federal funding to help reduce or eliminate duplication of effort Examine State/local cost share

OIR – GIS Services 9 Retreat 2007, 10/31/07 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

OIR – GIS Services 10 Retreat 2007, 10/31/07 FY 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to emulate “Imagery for the Nation” and local requirements Identify counties with significant growth, imagery that is outdated, TDOT region 1 (upper East TN) Continue operating under current cost share model (75% State / 25% local) Data Maintenance Strategies

OIR – GIS Services 25 Retreat 2007, 10/31/07 How can State agencies create and maintain spatial data once and use (share) it many times? The “Tennessee Map” (TNMap) Enterprise GIS Development

OIR – GIS Services 26 Retreat 2007, 10/31/07 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

OIR – GIS Services 27 Retreat 2007, 10/31/07 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)

OIR – GIS Services 28 Retreat 2007, 10/31/07 Business Case for Enterprise GIS 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 The Tennessee Map (TNMap): Enterprise GIS Architecture
