Milestones/Milestones/AccomplishmentsAccomplishmentsA few quick facts:A few quick facts:

• Collaboration/Local partnerships– $5 million in contracts– 250 organizations in 54 counties– Leveraged existing data in 6 counties– Local GIS maintenance in 42 counties– No Federal funding

• Total cost: $28 million– $19 million (ortho, DTM, planimetrics)– $ 9 million (parcels)


Current ActivitiesCurrent ActivitiesEnterprise GIS DevelopmentEnterprise GIS Development• Goals

– Develop enterprise GIS infrastructure to provide public access to TNBMP data

– Provide State agencies with option 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)– GeoPortal for accessing TNBMP data

and State agency GIS data via web services, GIS applications, related GIS services, other GIS related info

– Data Viewing Utility– Search for GIS data using Metadata

Current Activities:Current Activities:Ortho Maintenance Ortho Maintenance

• Wrapping up initial statewide production

• Imagery is 7 years old in some counties

• Population growth/development driving demand for new imagery

• Need a plan for ortho imagery update/maintenance


Ortho Maintenance Pilot Ortho Maintenance Pilot ProgramProgram2007-20082007-2008• FY07-08 Funding in place• Extend current contract from 10/07 to

10/08 and modify specs to emulate “Imagery for the Nation” and local requirements

• Identify counties with significant growth, imagery that is outdated

• Continue operating under current cost share model (75% State / 25% local)

• Satisfy State/local needs, in step with IFTN, scheduled regional acquisition save $$$

• OIR-GIS and TDOT developing MOU for digital ortho maintenance

• Aircraft capture analog aerial photography – Large scale engineering projects (site specific)

– Right-of-way corridor studies

– Regional planning efforts (1/4 of State annually)

• Planning to update current process/equip to create digital orthophotography

• FEMA Flood Map Modernization– Continue to provide TNBMP data– Production work ongoing– Saved TN $5M

• Census TIGER Modernization– Provided centerline data for 72 counties– Submit remaining counties by 8/1/07– TNBMP partnership resulting in $2 Million

savings– In Kind Service – County Commission Districts
