20. Tennessee Enhanced Elevation DataProject Background & National Context (Rich Grady) • This project is supported with funding from the Federal Geographic Data Committee (FGDC) Fifty States Initiative, Cooperative Agreement Program (CAP) • FGDC was formed by the Office of Management and Budget (OMB) for the coordination of Geographic Information and Related Spatial Data Activities, including the creation of the National Spatial Data Infrastructure (NSDI) • Statewide GIS programs (e.g. TNBMP) are criticalto success of NSDI • FGDC believes strategic and businessplanning will help build-out effective statewide programs • In partnership with National States Geographic Information Council (NSGIC) they created strategic & business planning guidelines

21. The National Spatial Data Infrastructure (NSDI)Framework Themes • Compilation and integration of consistent, high-quality nationwide data for 7 framework layers/themes: • Geodetic Control • Cadastral (parcels) • Political Boundaries • Hydrography • Imagery (orthos) • Elevation • Transportation (Air, Roads, Inland Waterways, Rail, Transit)

22. Fifty States Initiative: Effort to catalyze creation of NSDI Including the CAP grant funding this project Geospatial One-Stop / National Map/Geospatial Platforms Programs for developing, sharing and accessing nationwide data National Enhanced Elevation Assessment (NEEA) To measure and facilitate progress on the development of enhanced elevation data for the nation The National Spatial Data Infrastructure (NSDI)Relevant Federal Initiatives

26. Tennessee Business PlanningThe NSGIC Guidelines • One Strategic Plan, potentially many Business Plans • Strategic Plan • What and Why • Vision & Goals • The “big picture” and overall context • Business Plan • How, When, and How Much • Aimed at those that approve and fund • Details of specific initiative(s) emerge • Presented as a business case

27. Tennessee Business PlanningApplying the NSGIC Guidelines • Strategic and Business Plans are ‘living’ documents (i.e., planning is a process, and plans should evolve to account for changing conditions) • Case studies of actual experiences can help make the business case (especially if quantifiable, but also if they tell a meaningful story) • We’re going to build on what you’ve already done…and what others have done, too! • 1998 TN Base Mapping Program Business Plan • 2008 Enterprise GIS Business Plan • State of TN LiDAR Technical Specifications, Oct. 2010 (Preliminary)

28. Tennessee Business PlanningApplying the NSGIC Guidelines • And, we’re getting stakeholder input! • Interviews • Regional Forums

30. Tennessee Business PlanningSelected Interview Findings Coordination for statewide program is needed – there are many diverse stakeholders but common interests Justifications for state appropriations are needed Federal partnerships are feasible Need to find political support and a champion for initiative Application to flood preparedness and mitigation is key Need better terrain data for land development and flood plain management The public demands better data, for their own property investigations and self-sufficiency Improve efficiency of necessary field visits and allow more in-office analysis

31. Tennessee Business PlanningSelected Interview Findings (Continued) • Changes of 4-5 inches in elevation on the ground can make a big difference in flood prone flat areas • Flooding models are only as good as the data they use • Compare contours and topographic features from 40-50 year old USGS quadrangle maps to modern high resolution contours derived from recent LiDAR data • Awareness of LiDAR technology not widespread -- educate • Avoid “hit or miss” LiDAR acquisition on a piece meal basis • Bring regulators and developers together on something they can both use – better data • A common vocabulary and operating picture are both needed, and was lacking in the flood events of the past two years • “Everyone needs enhanced elevation data,” but who is going to pay for it?
