Mapping Gunfire in Washington DC

Washington DC's ShotSpotter system is a network of over 300 acoustic sensors that are used to detect the sound of gunfire in the city and triangulate the location of each shooting. The Washington Post has taken the data from the last eight years and mapped 39,000 outdoor gunshot incidents detected by ShotSpotter.

The DC ShotSpotter map is a heat map showing the hotspots in the city where gunfire has been detected by the acoustic sensors. The heat map is slightly misleading as the ShotSpotter network only covers parts of the city and is focused on neighborhoods with the most violent crime. The map however does show the hotspots in the districts where ShotSpotter is in use.
