Uses
Crowdmapping can be used to track fires, floods, pollution,[ crime, political violence, the spread of disease and bring a level of transparency to fast-moving events that are difficult for traditional media to adequately cover, or problem areas][ and longer-term trends and that may be difficult to identify through the reporting of individual events.][
During disasters the timeliness of relevant maps is critical as the needs and locations of victims may change rapidly.][
The use of crowdmapping by authorities can improve situational awareness during an incident and be used to support incident response.][
Crowdmaps are an efficient way to visually demonstrate the geographical spread of a phenomenon.][
