REDEFINITION OF UNIBEN CONTROLS FROM MINNA DATUM

ABSTRACT

Applications involving mapping, navigation, and spatial data require precise geodetic control networks. To preserve accuracy, control points must be redefined and become denser over time. With the help of cutting-edge GNSS methods, this project aims to redefine geodetic control at the University of Benin. The current control lacks redundancy and was created using conventional surveys years ago. RTK GNSS readings were used to map markers across the University and observe the new geodetic network. The new coordinates will be constrained by network adjustment computations to the location of the existing triangulation points. Data gathering utilized dual-frequency GNSS receivers for usage of the entire constellation of GPS, GLONASS, Galileo, and BeiDou satellites. The modified control network will give the university a current frame of reference that will allow for highly accurate mapping and geographical analysis. We will study quality control, error ellipses, and network accuracy data. The project will increase local geodetic proficiency in rigorous network adjustment and sophisticated GNSS control surveying. The network will be maintained and made more, dense using recommendations. The deliverables include the report, network database, and survey mark descriptions.
