Abstract
The Broken Hill - Menindee point located data set consists of 182 new and 20,514 old gravity stations all with terrain correction values included. The data set is included as a separate directory on the CD-ROM containing the May 2003 release of the National Gravity Database. See GeoCat entry # 47696. New gravity stations were acquired at a spacing of 2km x 2km. Old data are at various station spacings. The pre 2003 gravity data come from existing data held in Geoscience Australia's National Gravity Database. These data are sourced from various surveys that in the past were commissioned by either Geoscience Australia, NSW Dept of Mineral Resources or private industry. All data were used to ground truth airborne gravity data acquired over the same geographic area near Broken Hill.

This dataset release contains 20,696 point data values in the area extending from 31.68° S to -32.23° S and 141.24° E to 141.84° E. All data are provided in GDA94 coordinates. <p>The parameters of the point located data are: <br>Station spacing: various from 30 m to 2 km <br>Projection: Geodetic in latitude and longitude <br>Null value: blank <p>Gravity Datum <br>The gravity data as supplied are based on the IGSN71 datum and ISOGAL84 scale. The gravity unit used is micrometres per second squared. The height data are given in metres based on the Australian Height Datum (AHD). Gravity positions are given in datum GDA94.
