[null,null,null,"Sommario/riassunto","Electronic Distance Measurement This text gives an up-to-date introduction into electronic distance measurement (EDM) with a comprehensive review of modern equipment and procedures. It is excellently suited as a text for undergraduate and graduate students and an invaluable reference for practicing surveyors, geodesists and other scientists using EDM as a measuring tool. This fourth edition of a text first published in Sydney in 1978 is based on Rüeger's teaching experience at the University of New South Wales in Sydney, Australia. Introductory chapters provide an overview of relevant laws of physics and basic principles of different types of EDM instruments. The following chapters examine velocity corrections, derive geometrical reductions from first principles and explain the design of state-of-the-art electro-optical distance meters. The final chapters introduce reflectors, power sources and instrument errors, and conclude with measurement and analysis procedures for the calibration of distance meters."]
