Sites that may be precisely reoccupied (to within a few millimetres) by a gravity meter, for the purpose of tying gravity surveys to an absolute gravity datum. Precise location is facilitated by site photographs and sketches and descriptions in addition to coordinates; most of the latter are not sufficiently accurate on their own. Absolute gravity values at each station are for at least one of the following datums: Isogal65, Isogal84, Australian Absolute Gravity Datum 2007 (AAGD07). The stations have been established either by absolute gravimetry or multiple repeat loop measurements with respect to other base stations.<\/SPAN><\/P><\/DIV><\/DIV><\/DIV><\/DIV>", "summary": "Sites that may be precisely reoccupied (to within a few millimetres) by a gravity meter, for the purpose of tying gravity surveys to an absolute gravity datum.", "title": "Gravity Base Stations", "tags": [ "Gravity", "Geophysics", "Geoscience" ], "type": "", "typeKeywords": [], "thumbnail": "", "url": "", "minScale": 150000000, "maxScale": 5000, "spatialReference": "", "accessInformation": "Mineral Resources Tasmania", "licenseInfo": "
