Establishing A Three-Dimensional Geodetic Point Network Inside the University of Technology, Iraq - Baghdad

Abstract Geodetic networks play the most important role in the accuracy and reliability achieved for surveying and mapping applications. Since 1980, in most world countries, numerous geodetic control networks have been established for a wide range of mapping projects using Global Positioning System (GPS) technology. The main objective of this study is to create a highly accurate, multi-way control network that uses the latest Global Positioning System (GPS) devices and technologies. In this study, a network was established that consists of seven control points distributed in the University of Technology, Iraq - Baghdad, with distances ranging from 50-250 meters or more between the points. The heights above sea level for all control stations were determined using a leveling device and they were linked to the national network, allowing the creation of a geoid model. Accurate for the university in the future. This study presents the monitoring method, the results obtained, and the characteristics, standards, and specifications designed for the geodetic control network. It is expected that this network will improve the reliability of monitoring the deflections in building and the practical part of undergraduate and postgraduate studies The availability of the integrity of geodetic networks, will have a significant impact on the surveying and mapping activities of the University of Technology.
