Mapping Data, Geographic Information Systems

This chapter offers an introduction to geographic information systems (GIS) and provides examples of how this approach to data visualization can help evaluators better understand the context in which they are working, conduct a deeper analysis of the data, and communicate using maps to illustrate important findings and patterns. The chapter also discusses the limitations of this approach and offers suggestions for those interested in integrating GIS in their evaluation practice. © Wiley Periodicals, Inc., and the American Evaluation Association.
