Abstract:

This paper recounts the conventional geodetic accomplishments of the Defense Mapping Agency DMA and its predecessor organizations in Africa, beginning with the 30th Meridian Arc in the early 1950s and continuing through the 12th Parallel Survey, which was completed in 1970. Additionally, it identifies the modernization resulting from the many Doppler geodetic positions, referenced to DMAs precise Navy Navigation Satellite ephemerides, established to date throughout the continent. Further it provides a conceptual plan for accomplishing, through bilateral agreements with the countries involved unification of the African datum by means of future efforts of Doppler data acquisition and reductionadjustments of geodetic control.
