This basic introduction clearly explains the functions and procedures required in every survey (routine or otherwise), why it is done, and how it is accomplished. Readers will not only gain an appreciation for a survey, plat, or land description but will be able to evaluate it in its proper perspective, realize any inherent inadequacies or discrepancies that may exist, and have a much better idea of when a survey is needed to solve a problem or to obtain an approval. With a wealth of high-quality line drawings, this new edition has been expanded with 30% new material and fully updated to current practice and technology, including the use of GPS and GIS in land surveys and how technology should be interpreted in evaluating the quality and accuracy of a land survey.
