Gravity for the Redefinition of the American Vertical Datum (GRAV-D) Data Products 2012 publication 2013-02 revision 2017-09 revision International DOI Foundation (IDF) doi:10.25921/cjc9-bh63 NOAA National Centers for Environmental Information NCEI Metadata ID: gov.noaa.ngdc:GRAV-D_Collection NOAA National Centers for Environmental Information publisher NOAA National Geodetic Survey author NOAA National Geodetic Survey originator Within the NOAA National Ocean Service (NOS), the NOAA National Geodetic Survey (NGS) has a federal mandate to provide accurate positioning, including heights, to all federal non-military mapping activities in the USA. In 2007, the NGS embarked on the Gravity for the Redefinition of the American Vertical Datum (GRAV-D) Project, one of the most ambitious projects in the history of the agency. The gravity-based vertical datum resulting from this project is accurate at the 2 cm level where possible for much of the country. Available data include airborne and terrestrial survey information, gravity data, and gravity-based geoids or datums. This undertaking was driven by the fundamental connection between Earth’s gravity field and the very definition of ‘height’ itself. The specific goal of GRAV-D is therefore to model and monitor Earth’s geoid (a surface of the gravity field, very closely related to global mean sea level) to serve as a zero reference surface for all heights in the nation. Accurate heights are critical to many scientific endeavors, but particularly to understanding and protecting low-lying coastal ecosystems. completed historicalArchive NOAA National Centers for Environmental Information ncei.info@noaa.gov https://www.ncei.noaa.gov/contact NCEI Contact Information Information for contacts at NCEI. offline pointOfContact NOAA National Geodetic Survey Gravity Program Contact Information ngs.gravd@noaa.gov 8:00 - 5:00 ET pointOfContact irregular https://geodesy.noaa.gov/wp-content/uploads/2018/07/cover_sm2.png Cover for the GRAV-D Project Plan. png Earth Science > Solid Earth > Geodetics/Gravity > Gravity theme Global Change Master Directory (GCMD) Science Keywords 2020-01-09 publication 9.1 NASA Goddard Space Flight Center, Earth Science Data and Information System https://www.earthdata.nasa.gov/learn/find-data/idn/gcmd-keywords Global Change Master Directory (GCMD) Keywords The information provided on this page seeks to define how the GCMD Keywords are structured, used and accessed.
