Although much has been written on evidence-based policy making, this is the first volume to address the potential of GIS in this arena. GIS and Evidence-Based Policy Making covers the development of new methodological approaches, emphasizing the identification of spatial patterns in social phenomena. It examines organizational issues, including the development of new tools for policy making. This text brings together the results of researchers working across the entire spectrum of evidence-based policy making, focusing on the exploration for new data sources and examining ways to bring GIS-based methods to the public and to policy-makers.
