The Review and Development of the Nigerian Geodetic Control Network

The Nigeria Geodetic Networks were established using primarily triangulation, traversing, trilateration, doppler and levelling networks for numerous control requirements in both surveying national spatial reference networks. These have a number of inherent negative failings that affect its reliability usage. Various investigations identified many weaknesses the network, starting with origin other subsequent observational adjustment defects. Thus, need to obtain accurate consistent sets coordinates available space technology equipment update strengthen network has now become necessary. This work reviews status existing Networks, possible ways improve them are highlighted. further proposes strategy most set serve Geodesy Geodynamics research, referencing mapping activities country. proposed programme action improving these includes: re-observing new computations entire controls, selection suitably chosen system meet present future geodetic needs positioning.
