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)
