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.

The Second Edition of the popular Fundamentals of Crime Mapping: Principles and Practice walks readers through the research, theories, and history of GIS in law enforcement. This accessible text explains the day-to-day practical application of crime analysis for mapping. Factual data from real crime analysis is included to reflect actual crime patterns, trends, series and what an officer or analyst can expect to see when he or she sits down to analyze and apply concepts learned. Special topics discussed include: an up-to-date discussion of the current crime trends in rural and urban areas, the major ecological theories of crime, the notion of geographic profiling, empirical research using crime mapping tools, basic mapping terminology, and more. New to the Second Edition: • All exercises and examples have been updated to reflect ArcGIS 10.0 and Excel 2010. • Includes a workbook with engaging exercises to offer hands-on application of the material. • All exercises and graphics have been updated to account for ArcGIS 10.0 and Excel 2010, though all exercises and examples for Excel 2007 remain. • Contains a NEW chapter discussing the various types of policing, with an emphasis on the Compstat process, intelligence led policing, and problem-oriented policing.
