Change from ITRF92 epoch 1988.0 to ITRF2000 epoch 2004.0 in Mexico
Gonzalez Franco, Guido Alejandro and Raul Angel Gomez Moreno
The National Institute of Statistics, Geography and Informatics (INEGI), with the intention to keep an updated and modern Geodetic Reference Frame, has been performing the activities required to change from ITRF 92 epoch 1988.0 to ITRF 2000 epoch 2004.0. Among the mentioned activities are the creation and publishing of standards, network solution of station coordinates of the Active National Geodetic Network (RGNA), transformation of coordinates of the passive network and information dissemination of the change. The transformation of coordinates from ITRF 1992 epoch 1988.0 to ITRF 2000 epoch 2004.0 is mainly performed with transformation parameters defined by IERS and using a plate tectonics model. The dissemination of information is made through national and regional training of geodetic data users, showing the algorithm, the transformation procedure and the effects of frame change on geodetic and cartographic products, additionally by the INEGI Internet site users will be kept informed.
