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.

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.

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.

Geocomputation with R is for people who want to analyze, visualize and model geographic data with open source software. It is based on R, a statistical programming language that has powerful data processing, visualization, and geospatial capabilities. The book equips you with the knowledge and skills to tackle a wide range of issues manifested in geographic data, including those with scientific, societal, and environmental implications. This book will interest people from many backgrounds, especially Geographic Information Systems (GIS) users interested in applying their domain-specific knowledge in a powerful open source language for data science, and R users interested in extending their skills to handle spatial data. The book is divided into three parts: (I) Foundations, aimed at getting you up-to-speed with geographic data in R, (II) extensions, which covers advanced techniques, and (III) applications to real-world problems. The chapters cover progressively more advanced topics, with early chapters providing strong foundations on which the later chapters build. Part I describes the nature of spatial datasets in R and methods for manipulating them. It also covers geographic data import/export and transforming coordinate reference systems. Part II represents methods that build on these foundations. It covers advanced map making (including web mapping), "bridges" to GIS, sharing reproducible code, and how to do cross-validation in the presence of spatial autocorrelation. Part III applies the knowledge gained to tackle real-world problems, including representing and modeling transport systems, finding optimal locations for stores or services, and ecological modeling. Exercises at the end of each chapter give you the skills needed to tackle a range of geospatial problems. Solutions for each chapter and supplementary materials providing extended examples are available at https://geocompr.github.io/geocompkg/articles/. Dr. Robin Lovelace is a University Academic Fellow at the University of Leeds, where he has taught R for geographic research over many years, with a focus on transport systems. Dr. Jakub Nowosad is an Assistant Professor in the Department of Geoinformation at the Adam Mickiewicz University in Poznan, where his focus is on the analysis of large datasets to understand environmental processes. Dr. Jannes Muenchow is a Postdoctoral Researcher in the GIScience Department at the University of Jena, where he develops and teaches a range of geographic methods, with a focus on ecological modeling, statistical geocomputing, and predictive mapping. All three are active developers and work on a number of R packages, including stplanr, sabre, and RQGIS.

A revised and expanded new edition of the definitive English work on map projections. The revisions take into account the huge advances in geometrical geodesy which have occurred since the early years of satellite geodesy. The detailed configuration of the geoid resulting from the GEOS and SEASAT altimetry measurements are now taken into consideration. Additionally, the chapter on computation of map projections is updated bearing in mind the availability of pocket calculators and microcomputers. Analytical derivation of some map projections including examples of pseudocylindrical and polyconic projections is also covered. Work undertaken in the USA and USSR on the creation of suitable map projections obtained through numerical analysis has been included. The book concludes with a chapter on the abuse and misrepresentation of map projections. An invaluable reference source for professional cartographers and all those interested in the fundamental problems of mapping the Earth.

Geographic information systems (GIS) have become increasingly important in helping us understand complex social, economic, and natural dynamics where spatial components play a key role. The critical algorithms used in GIS, however, are notoriously difficult to both teach and understand, in part due to the lack of a coherent representation. GIS Algorithms attempts to address this problem by combining rigorous formal language with example case studies and student exercises. Using Python code throughout, Xiao breaks the subject down into three fundamental areas: Geometric Algorithms Spatial Indexing Spatial Analysis and Modelling With its comprehensive coverage of the many algorithms involved, GIS Algorithms is a key new textbook in this complex and critical area of geography.
