Resumo	Kernel density crime mapping turns a scatter of geocoded crime points into a smooth, continuous surface that shows where incidents concentrate. Each event is spread out over a small neighborhood by a kernel function, and the overlapping contributions are summed across a fine grid so that areas with many nearby crimes glow as peaks. Chainey, Tompson, and Uhlig (2008) showed that, among common hot-spot mapping techniques, kernel density estimation is one of the most accurate at predicting where future crime will occur, which is why it became the default crime-mapping surface in policing.	Crime mapping is the practice of geocoding crime incidents to their locations and using geographic information systems (GIS) to visualize and analyze where crime concentrates. It spans simple pin maps, area-based choropleth maps, and continuous density surfaces, and underpins the geographic side of modern crime analysis — from CompStat briefings to problem-oriented policing.
