Working with projections and datum transformations in ArcGIS

An invaluable aid for ArcGIS users, this book offers a blend of background information on projections and transformations alongside detailed explanations of their application in ArcGIS. As geodesy and GIS software have evolved, users increasingly face challenges with coordinate systems and projections. This resource addresses common issues, such as data misalignment and converting between UTM zones, providing clear, practical solutions. It emphasizes the execution of projections and transformations in ArcGIS, explaining when and why they are necessary, all without using formulae—making it a unique offering. Recognizing the gap between theory and practice, two GIS experts—a geodesist and a mathematician—crafted this guide. Following its successful launch in German, it is now accessible to the English-speaking ArcGIS community, coinciding with significant updates in ArcGIS 9 regarding projections and transformations. The book includes four practical chapters on coordinate system handling, customization, and programming techniques, along with theoretical chapters that provide essential background without overwhelming the reader. Chapter 8 features Frequently Asked Questions based on user support experiences, offering quick access to typical scenarios and solutions. With valuable tips for general users, administrators, and programmers, it caters to a diverse audience, from beginners to experienced developers looking to enhance Arc
