• Standard DTM = +/- 7 foot vertical accuracy

• 10 foot contour interval (ASPRS class II)

• Better than USGS 10M DEM, but didn’t meet all stakeholder needs

• 10 + years old in some counties

• New, cost effective technology advancements (LiDAR)

• Flood Events of 2010 and 2011

• Elevation needs beyond floodplain management

• 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 critical to success of NSDI• FGDC believes strategic and business planning will help build-out effective

statewide programs

• In partnership with National States Geographic Information Council (NSGIC) they created strategic & business planning 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

The NSGIC Guidelines

A p p l i e d G e o g r a p h i c s , I n c . / T e n n e s s e e R e g i o n a l F o r u m s / E n h a n c e d E l e v a ti o n / A u g u s t 2 0 1 1 S l i d e 2 7

Tennessee Business Planning Applying 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

Tennessee Business Planning Selected Interview Findings

a. Coordination for statewide program is needed – there are many diverse stakeholders but common interests

b. Justifications for state appropriations are neededc. Federal partnerships are feasibled. Need to find political support and a champion for initiativee. Application to flood preparedness and mitigation is keyf. Need better terrain data for land development and flood plain

managementg. The public demands better data, for their own property investigations

and self-sufficiency h. Improve efficiency of necessary field visits and allow more in-office

analysis

Tennessee Business Planning Selected Interview Findings (Continued)

i. Changes of 4-5 inches in elevation on the ground can make a big difference in flood prone flat areas

j. Flooding models are only as good as the data they usek. Compare contours and topographic features from 40-50 year old

USGS quadrangle maps to modern high resolution contours derived from recent LiDAR data

l. Awareness of LiDAR technology not widespread -- educatem. Avoid “hit or miss” LiDAR acquisition on a piece meal basisn. Bring regulators and developers together on something they can both

use – better datao. A common vocabulary and operating picture are both needed, and

was lacking in the flood events of the past two yearsp. “Everyone needs enhanced elevation data,” but who is going to pay

for it?
