Dynamic datums, which account for crustal dynamics, are widely used in Australia and New Zealand, although in many cases users may not be aware that they are using such a datum. The most widely-used global dynamic datums in Australia and New Zealand are the International Terrestrial Reference Frame (ITRF) and the World Geodetic System 1984 (WGS84). The use of WGS84 presents particular challenge...

There is a widespread misconception within the spatial science community that the three geocentric datums widely used in Australia, GDA94, ITRF and WGS84 are identical “for all practical purposes”. This is a fair assumption for navigation and many mapping purposes, however users of wide area differential GPS and precise positioning services with a precision of less than a metre are beginning to...

This paper is about a coordinate system problem for the “live” aspect of LVC training that impacts terrain reusability. Commonly used commercial software for producing correlated terrains has an outdated definition of datums that assumes that NAD83 and WGS84 are still equivalent, and does not take into account the newer realizations of these, or the fact that there have been significant plate t...

In the course of this paper, a by IFEN GmbH developed integrated navigation device for aiding and rescuing fire fighters in emergency situations is presented. In areas with sufficient signal strength the respective rescue force is tracked by means of GNSS/INS position information, whereas indoor or in areas without GNSS support, the positioning is conducted by means of a foot mounted inertial m...

The non-availability of ellipsoidal heights local geodetic Datums has made it necessary for the application transformation models to available global obtain their respective theoretical in Datums. It is required know accuracy, as well reliability any model interest before its application. For that reason, this study comparatively analyses Molodensky and Kotsakis between geocentric non-geocentri...

The Continuously Operating Reference Station (CORS) technique has been widely applied in land resource management, surveying, mapping, deformation monitoring, precise navigation, etc. This article analyzed the positioning method using EGM2008 and CORS of Jilin Province, China. The vertical transformation of EGM2008 from WGS84 to China's CGCS2000 datum and the horizontal coordinate transformatio...

The study site, l’etang de Piantarella, is located in Bonifacio, on the southern coast of Corsica (France). Three cores were extracted: Piantarella 1 (630 cm, WGS84: 41° 22ʹ 29.34″ N, 9° 13ʹ 12.62″...
