Crime Analysis: Heat Maps In Action
Crime Analysis in GIS Specifically using Esri software suite such as Arc GIS Pro to build crime heat maps to display significantly high areas of crime. This can be based on crime rates using population data or area data, or even using kernel density calculations to define local clusters of crime. Different algorithms such as Moran's I can define grid like hot spot areas of significant crime at a 95% confidence interval, allowing you as a GIS analyst to inform your command staff at your local Police Department the areas in which Patrol should focus their efforts. Defining a Crime Rate This map below is an example of calculating crime rate of a specific type of crime (Burglaries) in a specific area (Washington D.C.) using a standardization of population. We are calculating the number of Burglaries per 1,000 Housing Units. We started out using SQL Expressions and Table joins to select Burglaries from our crime point data, then joining the census data of population and housing un
