Understanding crime mapping and hot spots

Different kinds of hot spots, which develop from different causes, require different kinds of police action. Analysts may waste valuable resource time in their attempts to create a crime hot spot map if a test such as the NNI quickly reveals that no clusters, and thus no hot spots, exist in their data.

Continuous surface hot spot maps allow for easier interpretation of crime clusters and reflect more accurately the location and spatial distribution of crime hot spots. Also important to remember is that map production is an iterative process.

Much of crime mapping is devoted to detecting high-crime density areas known as hot spots. Hot spot analysis helps police identify high-crime areas, types of crime being committed, and the best way to respond.

The intended message should be seen as the driving force behind what the map should look like. Their choices of neighbourhoods, schools, shops, streets, and recreation are governed partially by the understanding that their chances of being a victim are greater in some of these places than in others.

The first map produced is very rarely the one presented to the target audience. Key Findings Identifying hot spots requires multiple techniques; no single method is sufficient to analyze all types of crime.

This report discusses hot spot analysis techniques and software and identifies when to use each one. Tests for clustering are particularly important. Preliminary global statistics have shown how simple-to-apply tests can reveal an understanding of what is to be expected in a hot spot map, even before the map has been created.

The different mapping techniques have revealed the different applications to which they are suited and demonstrated the advantages and disadvantages in their underlying routines and the mapping outputs they generate.

Current mapping technologies have significantly improved the ability of crime analysts and researchers to understand crime patterns and victimization. You need JavaScript enabled to view it. Map creation and design requires flexibility. In this example we show the total crime for the year within a one mile radius of the intersection of Oracle and Wetmore in Tucson, AZ.

The visual display of a crime pattern on a map should be consistent with the type of hot spot and possible police action. With this example, you can see that more crime is occuring in this area along the major roadways, and appear to be focused around shopping centers.Mapping Crime: Understanding Hot Spots Much of crime mapping is devoted to detecting high-crime-density areas known as hot spots.
