Sammanfattning	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.	Risk Terrain Modeling (RTM) represents crime risk as a function of the environment: it identifies the features of a landscape — bars, bus stops, vacant lots, pawn shops, schools — that attract or generate crime, maps each one's spatial influence as a separate risk layer, and combines those layers onto a raster of place to produce a relative risk surface. Introduced by Joel Caplan and Leslie Kennedy around 2011, RTM 'brokers' environmental criminology theory and GIS methods so that crime forecasting rests on the qualities of places rather than on the history of crime alone.
