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.

Flux Coordinates and Magnetic Field Structure gives a systematic and rigorous presentation of the mathematical framework and principles underlying the description of magnetically confined fusion plasmas. After a brief treatment of vector algebra in curvilinear coordinate systems the book introduces concepts such as flux surfaces, rotational transforms, and magnetic differential equations. The various specific types of coordinate system are dealt with in detail. Researchers and advanced students in plasma physics, electromagnetics, and mathematical physics will greatly benefit from this useful guide and reference book.

In Generalized Barycentric Coordinates in Computer Graphics and Computational Mechanics, eminent computer graphics and computational mechanics researchers provide a state-of-the-art overview of generalized barycentric coordinates. Commonly used in cutting-edge applications such as mesh parametrization, image warping, mesh deformation, and finite as well as boundary element methods, the theory of barycentric coordinates is also fundamental for use in animation and in simulating the deformation of solid continua. Generalized Barycentric Coordinates is divided into three sections, with five chapters each, covering the theoretical background, as well as their use in computer graphics and computational mechanics. A vivid 16-page insert helps illustrating the stunning applications of this fascinating research area. Key Features: Provides an overview of the many different types of barycentric coordinates and their properties. Discusses diverse applications of barycentric coordinates in computer graphics and computational mechanics. The first book-length treatment on this topic

"Computational Fluid Dynamics Based on the Unified Coordinates" reviews the relative advantages and drawbacks of Eulerian and Lagrangian coordinates as well as the Arbitrary Lagrangian-Eulerian (ALE) and various moving mesh methods in Computational Fluid Dynamics (CFD) for one- and multi-dimensional flows. It then systematically introduces the unified coordinate approach to CFD, illustrated with numerous examples and comparisons to clarify its relation with existing approaches. The book is intended for researchers, graduate students and practitioners in the field of Computational Fluid Dynamics. Emeritus Professor Wai-Hou Hui and Professor Kun Xu both work at the Department of Mathematics of the Hong Kong University of Science & Technology, Hong Kong, China.

Polar coordinates can be used in 3D as well as 2D. As you probably have already guessed, 3D polar coordinates have three values. But is the third coordinate another linear distance (like r) or is it another angle (like θ)?
