Download or read book Basic GIS Coordinates written by Jan Van Sickle and published by CRC Press. This book was released on 2017-07-06 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Coordinates are the foundation of GIS, cartography, and surveying, to name just a few fields. Computers have an astounding capacity for repetition and they possess a superior ability to handle the mathematics behind coordinate manipulation—but they are very bad at interpreting coordinates and coordinate systems. Basic GIS Coordinates, Second Edition clearly illustrates the basic principles of coordinate systems, covering ellipsoids, datums, and plane coordinates as they are used in GIS and GPS. Keeping in mind that it is ultimately incumbent on humans to ensure the correct use of coordinate systems, this book explains complex topics in a logical progression, presenting them in a way that is neither too complicated nor oversimplified. This new edition of a bestseller expands the material with updates on what has occurred in the field during the past five years, especially in the World Geodetic System and International Terrestrial Reference Frame. It also addresses the upcoming GNSS constellations and coordinate implications. Details how to build a coordinate system Addresses different methods of leveling, as well as measuring and modeling of height and gravity Explores two-coordinate (state-plane, UTM) systems Discusses initial points and other aspects of the rectangular system Covers the geoid and the concepts of elevation There are thousands of horizontal geodetic datums and Cartesian coordinate systems currently sanctioned by governments around the world to describe our planet electronically and on paper. Even if a computer has done nothing wrong, coordinate errors can often occur and lead to potentially disastrous miscalculations. This book is a valuable tool to help readers develop an understanding of how coordinate systems work—and how they sometimes don’t.
Download or read book Basic GIS Coordinates written by Jan Van Sickle and published by CRC Press. This book was released on 2004-05-27 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book GIS Basics written by Stephen Wise and published by CRC Press. This book was released on 2018-10-08 with total page 235 pages. Available in PDF, EPUB and Kindle. Book excerpt: Geographical Information Systems (GIS) are computer systems for storing, displaying and analyzing spatial data. The past twenty years have seen a rapid growth in their use in government, commerce and academia, and they can be used for managing a network of utilities, from handling census data through to planning the location of a new supermarket. But how do they work? Stephen Wise has been a regular contributor to GeoEurope and his 'Back to Basics' articles have provided a clear and simple introduction to the inner workings of GIS for a non-specialist audience. He now presents the original articles with new material and provides a new coverage of both major types of GIS: vector and raster systems. Undergraduates and professionals who wish to improve their knowledge of GIS should get a better understanding of how GIS operate in the way that they do, such as how spatial data is stored on a computer, how the different methods affect the capabilities of the GIS, how basic operations performed and how the choice of algorithm affects the speed of the system.

Download or read book Datums and Map Projections for Remote Sensing GIS and Surveying written by Jonathan Iliffe and published by CRC Press. This book was released on 2000 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: New methods of acquiring spatial data and the advent of geographic information systems (GIS) for handling and manipulating data mean that we no longer must rely on paper maps from a single source, but can acquire, combine, and customize spatial data as needed. To ensure quality results, however, one must fully understand the diverse coordinate frameworks upon which the data are based. Datums and Map Projections provides clear, accessible explanations of the terminology, relationships, transformations, and computations involved in combining data from different sources. The first half of the book focuses on datums, exploring different coordinate systems and datums, including two- and three-dimensional representations of Earth coordinates and vertical datums. After an overview of the global positioning system (GPS), the author introduces the fundamentals of map projections and examines the different types. He then presents models and procedures for transforming directly between data sets. The final chapter presents case studies of projects that illustrate the types of problems often encountered in practice. Newcomers to the field will welcome this treatment that, instead of detailed mathematics, uses lucid explanations and numerous examples to unravel the complexities of the subject. For more experienced readers, the book is a valuable reference that answers specific questions and imparts a better understanding of transformation operations and principles. Features
