1. 1 www.vita.virginia.gov Statewide Lidar Cost/Benefit Analysis Sam Hall Geospatial Projects Manager Virginia Geographic Information Network January 9, 2008 www.vita.virginia.gov 1

2. 2 Overview Virginia’s cost/benefit analysis process VGIN’s plan for developing a lidar cost/benefit analysis and current progress

3. 3 www.vita.virginia.gov Virginia’s Cost/Benefit Analysis Process

4. 4 www.vita.virginia.gov Factors to Consider Factors to consider when evaluating a statewide (or regional) lidar collection effort: –Business needs of a diverse group of users –Size, terrain, and accessibility of project area –Alternative technologies and data sources that may meet users’ needs –Cost/befit ratio of data collection –Funding plan

5. 5 www.vita.virginia.gov Virginia’s CBA Process

6. 6 www.vita.virginia.gov Virginia’s CBA Process Gather background information –Define project objectives –Document current or “as is” state –Estimate future requirements Identify and measure costs and benefits –Collect and document costs Document assumptions, choose three alternatives, estimate and document costs of all options –Identify and document benefits Identify and quantify tangible and intangible benefits

7. 7 www.vita.virginia.gov Virginia’s CBA Process (cont.) Analyze data –Compare alternatives –Conduct sensitivity and risk analyses –Calculate return on investment, payback, and net present value Document recommendation in a project proposal

8. 8 www.vita.virginia.gov VGIN’s Plan for Developing a Cost/Benefit Analysis for Lidar Collection

9. 9 www.vita.virginia.gov Gathering Background Information Lidar page on VGIN’s website (coming in January 2008) –General information about lidar –Document archive (minutes, presentations, etc.) –Lidar blog Survey of state and local government agencies (coming in January 2008) –Documenting current state, potential benefits, future needs –Survey will be accessible from VGIN website –Assistance from federal agencies and industry leaders

10. 10 www.vita.virginia.gov Gathering Background Information Targeted meetings after the survey Meetings with lidar vendors to review emerging technologies Reviewing the experiences of other states Lidar COIN or steering committee?

11. 11 www.vita.virginia.gov Identifying Costs and Benefits Gather benefits information via survey and targeted meetings Costs estimates will be based on a “Virginia Lidar Standard” that will meet most users’ needs (developed through meetings, lidar COIN, and/or steering committee)

12. 12 www.vita.virginia.gov Data Analysis and Project Proposal Tentative schedule: –Background information gathering and cost/benefit documentation complete by spring 2008 –Data analysis and project proposal complete by summer 2008
