Designed for users already familiar with GIS, this concise handbook invites students to think broadly about the assumptions embedded in GIS practice today.

"I very much appreciate the proposed appendices; the topics are elements that practitioners return to regularly. Having these reference pages will make looking up such information fast and simple." --Tarmo Remmel, York University

"The uniqueness of the book seems to be its more in-depth computational focus, as compared to most introductory GIS texts. . . . To me, the most valuable sections...are the ones marked 'Advanced'. The advanced chapter on Error and Uncertainty is particularly welcome as this topic is often poorly handled in other texts." --Janet E. Mersey, University of Guelph
