Crime mapping, email reports and tips for the public



Different views of the same data

Community Crime Map crime mapping and analysis interface displays four views of a city's crime data to the public. A simple tabbed interface allows the public to switch between a Map, Data Grid, Analytics and Metadata view of the crime data.


Community Crime Map displays limited crime data to the public in Google Maps' well known, intuitive mapping interface. Crime type, street-level address, location type and date and time are displayed for the public. Filtering capabilities include address search, buffer and date constraints.

Data Grid

Community Crime Map gives the user full control over how data is displayed. In "Data Grid" view users can turn on and off columns and sort data based on any variable. Data in the grid automatically updates based on the incidents displayed on the map.


Meaningful, visually stunning graphs help users visualize crime trends in their area. Graphs automatically update based on the data that is displayed on the map giving user's full control over what data they would like to analyze.


It is important for the public to feel confident in the data that they are viewing. Community Crime Map's Metadata tab displays useful information about the data that is being displayed. The source of the data, accuracy of points on the map and other useful information displayed in Community Crime Map help improve transparency and trust between law enforcement and the public.

Filters apply everywhere

Users can apply filters to the data to view only the information that matters most to them. The Sidebar in Community Crime Map includes a number of filters that help the user focus on a specific area, type of crime, or date range. As a user adjusts these filters, the filters automatically apply throughout the application.

Example: If a user applies a filter to the Crime Types sidebar menu to show only crimes that are Thefts, then only incidents that are classified as Thefts are displayed on the map. If the user switches to the Analytics tab, the graphs automatically adjust to display information only related to Thefts.
