1. A computer system comprising: a database storing historical crime incident data reflecting crime incidents that occurred over a past period of time; one or more computer readable media storing one or more software modules comprising computer executable instructions; one or more hardware processors in communication with the one or more computer readable media, and configured to execute a forecasting module of the software modules in order to generate a crime risk forecast based at least on the historical crime incident data stored in the database, the generated crime risk forecast being for a particular target geographic area, a particular future time window, and a particular crime type; the one or more hardware processors further configured to execute the forecasting module in order to generate a crime risk rating as part of generating the crime risk forecast; the one or more hardware processors further configured to execute a presentation module of the software modules in order to generate and display a graphical user interface overlay on an interactive geospatial basemap generated by a geospatial application, the overlay visually indicating the particular target geographic area of the generated crime risk forecast on the interactive geospatial basemap, the overlay visually indicating the particular future time window of the generated crime risk forecast, and the overlay visually indicating the particular crime type of the generated crime risk forecast; the one or more hardware processors further configured to execute the presentation module in order to generate and display, as part of the overlay, a visual indication of the generated crime risk rating; wherein the particular future time window corresponds to a particular future law enforcement patrol shift, the particular future law enforcement patrol shift corresponding periodically recurring continuous period of time; wherein the overlay visually indicates the particular future law enforcement patrol shift; wherein the overlay further visually indicates, for each of a plurality of periodically recurring continuous sub-time periods of the periodically recurring continuous period of time, a number of the historical crime incidents that occurred during the each periodically recurring continuous sub-time period and in the particular target geographic area.
