Lining Up Data in ArcGIS: A Guide to Map Projections,Second Edition, is an easy-to-navigate troubleshooting reference for any geographic information system (GIS) user who works with coordinate systems. Complete with full-color maps and diagrams, this book presents practical techniques to help readers identify data projections, create custom projections to align data, and resolve common issues.

The second edition is compatible with ArcGIS 10.1 and includes new sections on using CAD data and appropriate use of the web Mercator projection. While written specifically for users of ArcGIS, this book is a valuable reference guide for anyone working with map projections, coordinate systems, and data conversion.

Lining Up Data in ArcGIS: A Guide to Map Projections shows you:

• How to resolve alignment issues reflected in common error messages and warnings
• How—and when—to perform geographic transformations and which transformation to use
• How to decide which map projection to use
• What the parameters in a projection file mean and what they do
• How to add x,y data to your map

“I have found that data misalignment is one of the biggest issues faced by GIS users,” says author Margaret M. Maher, a specialist in projections and data conversion in Esri’s Support Services department. “While understanding coordinate systems can be a challenge, this book is filled with practical techniques that will demystify the process.”
