Introduction of New VGIN Staff• Stephen Barbie
– GIS Technical Services Specialist
• Kenny Brevard– GIS Analyst
• Michael Vojta– GIS Analyst
www.vita.virginia.gov 3
VGIN Coordinator’s Report• New approach – email out week prior to
Board meeting• Highlight key items during Board meeting• Provide opportunity to Board for questions
about any of the report
• Preferences? Other ideas?
www.vita.virginia.gov 4
DPOR Licensing – Surveyor Photogrammetrist• Public comment period closed 9/13/2007
– VGIN Coordinator notified one week prior
• VGIN Coordinator response – in Board packet– Essence of comments:
• Clearly define “acceptable use” of technology– Legal documentation that supports land surveying– Not prohibit use of technology for non-legal documentation
within government
• Other comments of concern from localities– http://townhall.virginia.gov/L/comments.cfm?stageid=37

• Standard Process– http://townhall.virginia.gov/UM/chartstandardbasic.pdf

2006/2007 Orthophotography Status• 2006 imagery (15% of state) received and
delivered to localities• Web service established for state agencies• Developing pricing structure for other entities
• 2007 imagery in process– Jurisdictional delivery schedule in Board packet– Developing plans to make imagery available to state
agencies as it is delivered through web services
www.vita.virginia.gov 6
2009 Orthophotography Needs Assessment
• Met individually with 7 state agencies with the largest GIS presence to determine “needs vs. wants” – see spreadsheet
• Will utilize ortho Community Of Interest – COIN for additional guidance
• Developing online surveys to capture additional needs
• VGIN will recommend the capture of one quarter of state per year– Provides more consistency, Better project management
www.vita.virginia.gov 7
2009 Statewide Data Capture Proposal• Commence in spring 2009• Capture one quarter of the state per year
– Shorter and more manageable product delivery schedule• Wide variance in geography and climatology• Reduced logistical issues with statewide capture
– Recurring annual data capture and processing• More predictable budgeting and forecasting
• Provide upgrade options– Utilize digital sensors so that options are available such
as Lidar, multi-spectral– Provide resolution upgrades– Ability to capture geographic areas outside of planned
data capture areas

• What is LiDAR ?• Why is it important?
• Possible Board agenda item for more in depth analysis for January meeting

LiDAR• Gives you highly accurate Surface Models
www.vita.virginia.gov 16
Light Detection And Ranging (LiDAR) Needs Assessment• Potential to satisfy “elevation” base map
component for Virginia• Sample application uses include emergency
management, disaster preparedness, and environmental impact from sea level rise
• Virginia lacks statewide LiDAR compared to neighboring states, leaving a “hole” in the regional coastline
• Increased interest from coastal zone, state geologists and some localities
• State & Federal interest group met in August to discuss shared needs
www.vita.virginia.gov 17
Advise from the Board• LiDAR is expensive but proving to be critical.
With LiDAR’s growing importance VGIN could:– Develop a cost benefit analysis– Continue needs assessment– Elevate its priority based upon user needs
– What is the best way to build a case for a funding?– What possible funding vehicles, if any, may be available?– Other advise?
www.vita.virginia.gov 18
Community Of Interest - COIN• Base Mapping COIN
– Over arching user input vehicle– Individual COINs for Framework Base Mapping Themes:
– Orthoimagery– Transportation– Hydrography– Cadastral information– Governmental units– Elevation– Geodetic control
– Specialty areas as needed• e.g. Emergency Management, LiDAR
www.vita.virginia.gov 19
Diverse Representation
• Ideal: representation from all sectors
• Seek out specialists
• VGIN to facilitate and coordinate
www.vita.virginia.gov 20
Next Steps• Orthophotography COIN being assembled• VGIN website will disseminate information
– http://www.vgin.virginia.gov
• VGIN Listservs to disseminate information– State agencies– Local governments– VGIN Announce
• Utilization of Online Surveys
