This paper concerns the subject geodetic networks data in Iraq and the need to put them in specialized spatial databases that can be updated and developed, which makes it much easier for those concerned such as scientific researchers ad surveying engineers to access these data and use them in scientific applications and Engineering projects. The practical aspect of this study was divided into three stages, the first stage was limited to the collection of official data related to the main

The second stage consists of sorting the data obtained from the first stage, and then entering the selected data into spatial databases. The third stage includes the reconnaissance, ground survey and verification of data obtained from the second stage. Furthermore, it also showed that all the English networks, the first 1934 and the second 1967, as well as the points of gravity were almost completely extinct and it became difficult to identify any traces of any of its points within this region.
