A Guide to Understanding Land Surveys, 3rd Edition
December 2008, ©2009
Over the last several decades, the Internet has allowed individuals with a non-technical background to assume more control of land surveys. But without a clear understanding of how to accurately use land survey data, and faced with the challenges of communicating specific requirements to a professional land surveyor, conflicts often arise that lead to litigation.
A Guide to Understanding Land Surveys bridges the ever-expanding communication gap between the users of land boundary information and professional land surveyors.
This indispensable guide clearly explains the functions and procedures required in every survey (routine or otherwise), and the role of a surveyor in their investigation and re-establishment. It is a must-have resource for title attorneys, paralegals, realtors, government agents, and others who rely on the information gathered and presented by land surveys.
Written in nontechnical language and supported by numerous line drawings, A Guide to Understanding Land Surveys not only helps readers gain a strong familiarity with a survey, plat, or land description, but enables them to accurately evaluate it, detect any inadequacies, and make the proper adjustments to obtain approval.
The Third Edition of A Guide to Understanding Land Surveys has been expanded with thirty percent new material and is fully updated to reflect the latest practice guidelines and technology, including the use of GPS and GIS in land boundary re-establishment. Also included is important new material on how technology should be interpreted in assessing the quality and accuracy of a land survey.
