Elevation Requirements Meeting
Status of Elevation Program - NGPO/USGS
• Requirements for FY2008 and beyond
Status of NED VA Elevation • USGS elevation requirements over Virginia
Acquisition StrategyDrivers• Emergency response and homeland security
issues• National science priorities • Need for finer resolution elevation data in
support of internal and user community needs• Closer alignment with orthoimagery needs and
acquisitions• Graphic requirements
Elevation Requirements Meeting
Acquisition StrategyTNM and Director’s requirements• Elevation to support contours for 7.5 minute
graphic products (Image and Topographic map) deep from coastline– FY08 – Gulf and southern east coast, some science-
related projects, border– FY09 – northern east coast, west coast, science-
related projects and borders

Acquisition StrategyTNM and Director’s requirements (cont)• Base data to underpin Director’s Science
strategy as detailed in Circular 1309, Facing Tomorrows Challenges-US Geological Survey Science in the Decade 2007(http://sofia.usgs.gov/publications/circular/1309/)
– Climate change– Energy and materials– National hazards
Elevation Requirements Meeting
Acquisition StrategyOther requirements
• DOI Healthy Lands programs
• State and local• NED update
– 1/9 arc second (3m)– 1/3 arc-second (10m) from 1/3 acquisitions and TVCs– 1 arc-second (30m) from 1/9 and 1/3 data
Elevation Requirements Meeting
Virginia NED status • Poor – mainly 10m data from 30m source• Some TVC work in progress• NGA UA lidar: 1m, core UA footprints
– Richmond – Norfolk– Williamsburg– Northern Virginia (part of DC coverage)
