NGS's Gravity Survey Data Released to the Public

The week of September 5, NGS announced the first public release of airborne gravity data as part of its Gravity for the Redefinition of the American Vertical Datum (GRAV-D) Project. The released data block contains airborne gravity lines collected during the Alabama 2008 survey flown from Montgomery, Alabama in January and February, 2008 aboard the NOAA Cessna Citation II aircraft. The data block covers a 100 km x 400 km area of the Gulf of Mexico and a small portion of the Alabama coastline. This data release also marks the roll-out of a new GRAV-D data Web-portal, with a GoogleMap interface. The GoogleMap will allow easy browsing of airborne gravity datasets that are in all stages of survey planning, data collection, data processing, and public data release. The GRAV-D gravity data may be downloaded via the "Data Products" link on the GRAV-D web site here. For more information, contact Theresa Diehl.
