Although sophisticated turnkey systems have virtually replaced hands-on work in the field, geospatial surveyors still have to plan and organize the work as well as remain responsible to clients and defend the work if necessary. Therefore, basic geometric principles, proper instrumental calibration, the analysis of data, and the presentation of results remain relevant. Since most practical work is carried out by prescribed systems and processed by software packages, Principles of Geospatial Surveying focuses on the essential principles users need to know, verifiable results of the work, and knowledgeable assessments of the results. The book outlines the fundamentals of geospatial surveying and includes relevant worked examples using Excel spreadsheets.
