Airborne Gravity: NGS' Gravity Data for EN04 (2013)
type: Dataset
description: Airborne gravity data for Michigan and Lake Huron collected in 2012 over 1 survey. This data set is part of the Gravity for the Re-definition of the American Vertical Datum (GRAV-D) 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. The data is available at http://www.ngs.noaa.gov/GRAV-D/data_en04.shtml in ASCII text format.
