In the determination of an improved geoid over Zambia, the Modified Stokes’ formula employing the RCR technique was used. The formula combined EGM2008 data, terrestrial classical free-air gravity anomalies over Zambia, and the SRTM 3′′ DEM over Zambia which represent the long, intermediate, and...
Download PDF ↓The diversity of datums in use today and the technological advancements that have made possible global positioning measurements with sub-meter accuracies, require careful datum selection and careful conversion between coordinates in different datums. This is due to different positional accuracies...
Download PDF ↓Geodetic Deformation Monitoring (GDM) plays a vital role in project safety and management. Geodetic measurements on dams are done to monitor change and rate of change in order to ensure safety. Kariba Dam suffers normal stresses, and strains mainly from temperature and hydrostatic pressure...
Download PDF ↓Planet Earth is approximately spherical in shape, and is three dimensional. To map the Earth on a flat piece of paper, in two dimensions, a map projection must be carried out. A map projection is a mathematical technique of how to represent the Earth’s curved surface on a flat surface. In Zambia,...
