Full Citation Examples
Gravity for the Re-definition of the American Vertical Datum (GRAV-D) is a project initiated by NOAA's National Geodetic Survey to collect and monitor gravity data suitable for the re-definition of the vertical datum for at least the United States and territories. Airborne gravity data will be collected from 2008-2022, processed, and released periodically in geographic blocks. Each block is comprised of one or more surveys. The data will be available at http://www.ngs.noaa.gov/GRAV-D/data_products.shtml in ASCII text format. Some data collection has and will be done in conjunction with partners, such as the US Geological Survey, National Geospatial-Intelligence Agency, Bureau of Land Management, and the Naval Research Laboratory.

Abstract: |
Gravity for the Re-definition of the American Vertical Datum (GRAV-D) is a project initiated by NOAA's National Geodetic Survey to collect and monitor gravity data suitable for the re-definition of the vertical datum for at least the United States and territories. Airborne gravity data will be collected from 2008-2022, processed, and released periodically in geographic blocks. Each block is comprised of one or more surveys. The data will be available at http://www.ngs.noaa.gov/GRAV-D/data_products.shtml in ASCII text format. Some data collection has and will be done in conjunction with partners, such as the US Geological Survey, National Geospatial-Intelligence Agency, Bureau of Land Management, and the Naval Research Laboratory. |
Purpose: |
These data sets were collected and processed by NOAA's National Geodetic Survey (www.ngs.noaa.gov) as part of its GRAV-D effort to modernize the U.S. vertical datum. The purpose of these data is to provide accurate gravity data for geoid modeling for the U.S. and its territories. It was designed to provide medium wavelength gravity information (around 20-400 km) to connect satellite and ground gravity measurements. |
