Modelamiento geométrico del cambio de coordenadas UTM causadas por mudanza de referencial geodésico: Caso Sirgas - Chile

Technological advances in recent decades have allowed determining with increasing precision, parameters related to size, shape and gravitational field of the Earth. These new technologies and methods of observation and analysis, accept the use of different Geodetic Reference Systems (GRS) that enable the description of position of any point on Earth's surface with sub-metric precision. Currently in Chile there are several SGR used in the generation of cartographic products, such as the Provisional South American Datum of 1956 (PSAD56), the South American Datum 1969 (SAD69) and the new Geocentr...
