"Based on the success of the previous four editions, this new edition includes Global Navigation Satellite Systems (GNSS) in the title, of which GPS is part. Neither simplistic nor overly technical, the new edition is updated with the changes in GPS and GNSS hardware, software, and procedures. It describes why modern GNSS positions can be acquired with more certainty, with increased stability, and improved tracking in obstructed areas. The book offers a rare combination of knowledge and skills that every land surveyor needs to master. Intended for both ingenues and professionals in the field, broad concepts are explained in an accessible way"--

Although part of nearly all real estate transactions, the land survey is one of the least understood elements in the process. Bringing together experts in commercial real estate law, title insurance, surveying, civil engineering, and lending, this is a clearly written explanation of all aspects of land surveys. Experts share their advice on critical questions to ask when reviewing a survey and address recent development in survey requirements and technology.

The nonsurveyor's definitive land survey sourcebook—now extensively updated 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.

Coordinates are integral building tools for GIS, cartography, surveying and are vital to the many applications we use today such as smart phones, car navigation systems and driverless cars. Basic GIS Coordinates, Third Edition grants readers with a solid understanding of coordinates and coordinate systems and how they operate as well as valuable insight into what causes them to malfunction. This practical and comprehensive guide lays out the foundation of a coordinate system and the implications behind building it as it elaborates on heights, two coordinate systems, and the rectangular system.The previous editions described horizontal and vertical datums such as the North American Datum 1983 (NAD 83) and the North American Vertical Datum 1988 (NAVD 88). Both will be replaced in 2022 or thereabouts. The National Geodetic Survey (NGS) plans to replace NAD83 with a new semi-dynamic terrestrial reference frame for North America and a new vertical datum will replace NAVD88. The foundation of the new vertical datum will be a temporally tracked gravimetric geoid. The interim period is intended to smooth the transition to the new paradigm and this new edition explores the changes and provides assistance in understanding them.

The only modern guide to interpreting and writing real property descriptions for surveyors Technical land information is no longer the exclusive domain of professional surveyors. The Internet now houses a multitude of resources that nontechnical professionals—such as attorneys and realtors—access and implement on a daily basis. However, these professionals are trained in aspects of law and commerce that do not provide the proper education and experience to interpret and evaluate their land boundary information discoveries correctly. As a result, their analysis is often erroneous and the data misapplied—ultimately leading to confusion and costly litigation. Professional Surveyors and Real Property Descriptions attempts to bridge the ever-widening gap between the users of land boundary information and the land surveyors who produce it. An expert team of authors integrates the historic and legal background of real property interests with fundamental concepts of the surveying profession in a manner accessible for average readers. These provide the basics for both properly comprehending older descriptions and competently constructing complete and modern real property descriptions that foster better communication. Highlights in this book include: An in-depth exploration of historic descriptions and how to read them Coverage of the widely accepted ALTA/ACSM Land Boundary Survey standards and associated property descriptions A diverse collection of examples and practice scenarios An overview of the latest issues related to the use of GPS and GIS Written in easy-to-understand language, this practical resource assists nontechnical professionals in understanding exactly what a surveyor does and does not do, and serves as a valuable tool for obtaining the most satisfactory, accurate, and complete real property descriptions.
