There are three main incident visualisation types in the IMS: Marker, Cluster and Heatmap. You can switch between them using the Type icon on the right hand side of the map.
The Marker map shows the incidents colour-coded by incident type. This shows incidents in their exact location.
The Cluster map aggregates incidents based on their location and your selected radius. A larger circle size represents a larger number of incidents in that area.
The Heatmap is another useful tool for visualising incidents. In this example, the red areas represent places in Iraq with the highest count and concentration of incidents.
