GPS and GIS Technology Changing the Culture of Navigation

Time, technology and user needs are constantly changing the way we do things, often making them easier and less expensive. When two great technologies are combined, a new innovation is created. Such is the case with GPS and GIS - into a fabulous little tool called the Personal Navigation Device. As is the case with many inventions, it changes the way we traditionally did things forever. But is that a good thing? Eva Dodsworth, Geospatial Data Services Librarian at the University of Waterloo Map Library, wonders.

Designed Maps: A Sourcebook for GIS Users
This sequel to the highly successful Designing Maps, offers a graphics-intensive presentation of published maps, providing cartographic examples that GIS users can then adapt for their own needs. Each chapter characterizes a common design decision and includes a demonstration map, which is annotated with specific information needed to reproduce the design, such as text fonts, sizes and styles; line weights, colors, and patterns; marker symbol fonts, sizes, and colors; and fill colors and patterns. Visual hierarchies and the purpose of each map are considered with the audience in mind, drawing a clear connection between intent and design. The book also includes a valuable task index that explains what ArcGIS 9 tools to use for desired cartographic effects. From experienced cartographers to those who make GIS maps only occasionally, all GIS users will find this book to be an indispensable resource. From ESRI Press, 2008.

Two-dimensional Signal Analysis
Exploring signal processing using a two-dimensional (2-D) spectral approach and addressing the modeling of 2-D signals, this text investigates the physical parameters and data-oriented analysis techniques associated with electronic waveforms. Chapters discuss numerous aspects of 2-D signals, including linear modeling, spectral analysis, and wavelength representation. Designed for students, scientists, researchers, and engineers, this study focuses on images from physical sensors such as radar and sonar. From ISTE Publishing Company, 2008.

Principles of Geospatial Surveying
Although sophisticated turnkey systems have virtually replaced hands-on work in the field, geospatial surveyors still have to plan and organize the work as well as remain responsible to clients and defend the work if necessary. Therefore, basic geometric principles, proper instrumental calibration, the analysis of data, and the presentation of results remain relevant. Since most practical work is carried out by prescribed systems and processed by software packages, Principles of Geospatial Surveying focuses on the essential principles users need to know, verifiable results of the work, and knowledgeable assessments of the results. The book outlines the fundamentals of geospatial surveying and includes relevant worked examples using Excel spreadsheets. From Whittles Publishing, 2008.
