Book excerpt: Crime Mapping Case Studies: From Research to Practice provides a series of key examples from practice and research that demonstrate applications of crime mapping and its effect in many areas of policing and crime reduction. This book brings together case studies that show how crime mapping can be used for analysis, intelligence development, monitoring performance, and crime detection and is written by practitioners for practitioners. Leading researchers in the field describe how crime mapping is developing and exposing analytical methodologies and critiquing current practices. Including global case studies that demonstrate a particular application, analytical technique or new theoretical concept, this text offers a truly global overview of this rapidly growing area of interest. Unlike other texts on this topic, this book identifies mistakes and challenges in this field of enquiry to aid the reader in understanding the basics of this technique, giving them the opportunity to learn further.
