The National Oceanic
and Atmospheric Administration (NOAA) and the U.S. Geological Survey (USGS) are
conducting a 3D Nation Elevation Requirements and Benefits Study. This study
will gather information to improve the availability and consistency of 3D
elevation data (topographic or bathymetric data) for the United States and its
territories using an on-line questionnaire. 
The questionnaire is part of the effort to develop and refine future
program alternatives that would provide enhanced 3D elevation data to meet many
federal, state, and other national business needs. For more information contact: Drew Decker, USGS  ddecker@usgs.gov
