Crime mapping is used by analysts in law enforcement agencies to map, visualize, and analyze crime incident patterns. It is a key component of crime analysis and the CompStat policing strategy. Mapping crime, using Geographic Information Systems (GIS), allows crime analysts to identify crime hot spots , along with other trends and patterns.
In geographic information systems (GIS) and spatial analysis, buffer analysis is the determination of a zone around a geographic feature containing locations that are within a specified distance of that feature, the buffer zone (or just buffer). [1] A buffer is likely the most commonly used tool within the proximity analysis methods. [2]
The theoretical foundation of geographic profiling is in environmental criminology. [5] Key concepts include: Journey-to-crime; Supports the notion that crimes are likely to occur closer to an offender’s home and follow a distance-decay function (DDF) with crimes less likely to occur the further away an offender is from their home base.
Furthermore, is an indicator function that returns 0 when a point (,) is an element of the buffer zone B (the neighborhood of a criminal residence that is swept out by a radius of B from its center). The indicator ϕ i j {\displaystyle \phi _{ij}} allows the computation to switch between the two terms.
A buffer zone, also historically known as a march, is a neutral area that lies between two or more bodies of land; usually, between countries. Depending on the type of buffer zone, it may serve to separate regions or conjoin them. Common types of buffer zones are demilitarized zones, border zones and certain restrictive easement zones and green ...
First, crime incidents are geocoded on a map, and then the distance between one crime incident and its neighbor is calculated. Following that all the distances are added up and divided by the number of crime incidents on the map. According to Eck et al. (2005) this value is called the observed average nearest neighbor distance. Then a map of ...
The definition of a violent crime turns out to be highly arbitrary, though. Burglaries are treated as violent, for example, even if no one is hurt or threatened, but most assaults don’t qualify ...
This glossary of geography terms is a list of definitions of terms and concepts used in geography and related fields, including Earth science, oceanography, cartography, and human geography, as well as those describing spatial dimension, topographical features, natural resources, and the collection, analysis, and visualization of geographic data.
