This is the only book on the market designed to provide readers with an introduction to geodesy without the usual emphasis on complex mathematics. Describes such positioning techniques as horizontal and vertical geodetic datums. Satellite geodesy, electromagnetic distance measurement, laser ranging and emerging technologies including the global positioning techniques and GIS are among the topics discussed. Features scores of two-color diagrams and examples to facilitate understanding.
