CRIME RISK FORECASTING
A computer-based crime risk forecasting system and corresponding method are provided for generating crime risk forecasts and conveying the forecasts to a user. With the conveyed forecasts, the user can more effectively gauge both the level of increased crime threat and its potential duration. The user can then leverage the information conveyed by the forecasts to take a more proactive approach to law enforcement in the affected areas during the period of increased crime threat.

based, at least in part, on the crime incident data, predicting a crime risk for a geographic area, a time window, and a crime type;
wherein the time window is in the future relative to the period of time over which the crime incidents occur;
generating and displaying a graphical user interface overlay on an interactive geospatial basemap;
wherein the interactive geospatial basemap is generated by a geospatial application; and
wherein the graphical user interface overlay visually indicates at least all of:
the geographic area,
the time window,
the crime type,
