'Lining Up Data in ArcGIS: A Guide to Map Projections is an easy-to-navigate troubleshooting reference for any GIS user with the common problem of data misalignment. Complete with full-color maps and diagrams, this book presents practical techniques on how to identify data projections, create custom projections to align data, and solve common data alignment problems. The second edition is compatible with ArcGIS 10.1 and includes new sections on aligning CAD data and appropriate use of the web Mercator projection. This book will benefit new and experienced GIS users alike'-- Chapter 1.
