Nowadays, geodetic networks and satellite geodesy are used.
2.
Nowadays, the method is replaced by worldwide geodetic networks and by satellite geodesy.
3.
Standards control accuracy, surveying credentials, monumentation of boundaries and maintenance of geodetic networks.
4.
A method of establishing precise metrologically traceable scale for geodetic networks measured by these instruments . ( This method has been superseded by GPS .)
5.
The NTSLF comprises the UK National Tide Gauge Network, geodetic networks, and gauges in the British Dependent Territories of the South Atlantic and Gibraltar.
6.
The HGRS87 datum is implemented by a first order geodetic network, which consists of approximately 30 triangulation stations throughout Greece and is maintained by the Hellenic Military Geographical Service.
7.
Many methods exist for determination of the axes of an Earth ellipsoid, ranging from meridian arcs up to modern satellite geodesy or the analysis and interconnection of continental geodetic networks.
8.
His work included research in statistics, deformation measurements, variance-covariance estimations in geodesy and immobiles, optimization of geodetic networks and datum transformations of geodetic systems, and satellite altimetry.
9.
The Bessel ellipsoid was derived in 1841 by Friedrich Wilhelm Bessel, based on several meridian arcs and other data of continental geodetic networks of Europe, Russia and the British Survey of India.
10.
Measurements can be made with a compass and topographic map ( or nautical chart ), Theodolite or with a total station using known points of a Geodetic network or landmarks of a map.
