Crime maps have only recently begun to emerge as a significant tool in crime and justice. Until a decade ago, few criminal justice agencies had any capability for creating crime maps, and few investigators had the resources or patience to examine the spatial distribution of crime. Today, however, crime mapping is experiencing what might be termed an explosion of interest among both scholars and...

Problem solving is one of the key components of CAPS. In Chicago, police and thousands of neighborhood residents have been trained to respond to local problems using a fivestep process. It involves identifying and prioritizing problems; analyzing them following the “crime triangle”; designing strategies to deal with the chronic character of priority problems; implementing the plan; and evaluati...

Crime opportunities are neither uniformly nor randomly organized in space and time. As a result, crime mappers can unlock these spatial patterns and strive for a better theoretical understanding of the role of geography and opportunity, as well as enabling practical crime prevention solutions that are tailored to specific places. The evolution of crime mapping has heralded a new era in spatial ...

For two decades crime rates, particularly for violent crimes, have been declining across the globe. Homicide rates, the best-measured violent crime, are down by 50% or more in many Western European countries and in the US. The crime drop is not limited to wealthy western countries. Over the past 20 years the homicide rate in large numbers of developing countries has declined by two-thirds or more.

there are often differences in data structure designs, data encoding approaches, data accessing and processing methods for these two types of geographic phenomena. Geographic coverage is a concept for continuous phenomena. Geographic coverage standards defines conceptual schema for coverage and analyze coverage types and components, e. g., [1]. These include characteristics of spatiotemporal do...

This paper explores some of the more recent developments within crime mapping and the broader application of geographical information technology within law enforcement. The information technology (IT) revolution and the reduction in computing costs since the 1980s has brought a range of analytical tools within the budgets of most police services, and one of the most significant changes has been...
