Abstract

Extcnsion of existing geodetic control using traditional terrestrial techniques has become
impractical nowadays as far as the time and the cost are concerned. And with the wide spread use
of GPS in geodesy the combination of GPS data with the existing terrestrial data is essential to
improve and enhance the quality of terrestrial geodetic control networks. This research paper
presents a methodology for combination of the Egyptian fust order terrestrial geodetic control
network with GPS points. The standard deviations will be used as a precision criteria. A numerical
example is presented. '
