Display Field: ID

Geometry Type: esriGeometryPoint

Description: This data represents all ShotSpotter incidents that were classified as “Probable Gunfire”, “Single_Gunshot”, or “Multiple_Gunshots” occurring within one of the six coverage areas defined below since January 1, 2014. The Department plans to continue to release this data with quarterly updates. Classifications are assigned by ShotSpotter and represent their assessment of what kind of impulse noise occurred. Some impulses initially dismissed as non-gunfire are manually audited and resubmitted to the dataset after ground truth analysis. MPD began implementing the ShotSpotter system in 2006 and has added sensors and upgraded components of the system at various times. ShotSpotter has also enhanced their ability to distinguish gunshots from other impulse noises. For example, the number of impulse noises coded as gunshots during Independence Day celebrations have significantly decreased over the past four years. ShotSpotter does not provide coverage for the entire District of Columbia. Official coverage areas are designed by ShotSpotter in conjunction with MPD, to target high population density areas with frequent sounds of gunshots incidents. A ShotSpotter incident may involve one gunshot or multiple gunshots depending on the time elapsed between each shot. Each incident is given a serial number ID when it occurs. The Latitude and Longitude of the incidents are rounded to three decimal places due to privacy concerns. This roughly corresponds to a 100 meter resolution.
