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.

Computers tend to be very good at repetition and very bad at interpretation. People, on the other hand, are poor at repetition, because we can get bored or distracted. We are, however, excellent at interpretation, if we have the proper information. Basic GIS Coordinates is about providing some of the critical information needed to understand coordinate systems and effectively interpret GIS technology. GIS is emerging in all facets of business and government at an incredible rate; GIS and mapping professionals must have a clear understanding of coordinate systems. Basic GIS Coordinates explains how coordinates tie the real world to its electronic image in the computer. It is about understanding how these systems work, and how they sometimes don't work. It examines how points that are expected to be in one location are in reality somewhere completely different, even when the computer has done everything exactly as it was told. Basic GIS Coordinates explains the progression of ideas that are the foundation of coordinate systems without overwhelming you with supporting mathematics. It is a user-friendly study for those who need to apply GIS technology and resulting coordinates. From the basics of coordinate systems to specific practical examples, this book covers GIS coordinates without pages of complicated math; yet it is not oversimplified. This volume analyzes state plane coordinates, UTM coordinates, and the rectangular system in a concise format. To help you apply the information, each chapter concludes with review questions and answers.

Traditional methods for handling spatial data are encumbered by the assumption of separate origins for horizontal and vertical measurements, but modern measurement systems operate in a 3-D spatial environment. The 3-D Global Spatial Data Model: Principles and Applications, Second Edition maintains a new model for handling digital spatial data, the global spatial data model or GSDM. The GSDM preserves the integrity of three-dimensional spatial data while also providing additional benefits such as simpler equations, worldwide standardization, and the ability to track spatial data accuracy with greater specificity and convenience. This second edition expands to new topics that satisfy a growing need in the GIS, professional surveyor, machine control, and Big Data communities while continuing to embrace the earth center fixed coordinate system as the fundamental point of origin of one, two, and three-dimensional data sets. Ideal for both beginner and advanced levels, this book also provides guidance and insight on how to link to the data collected and stored in legacy systems.

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.
