The Geo Dashboard of WSO2 CEP is a Jaggery application that provides realtime information about geo spatial objects. It processes spatial data from an external source of events and analyzes/manipulates this data to produce meaningful information to end users using the geo dashboard. You can interact with it to generate a variety of alerts and warnings as follows.

Alert type
Description
Speed alertYou can specify a maximum speed limit to all spatial objects. If an object exceeds the specified speed, an alert will be generated.
Proximity alert You can specify a radius and a time. Thereby, a warning will be populated if two spatial objects arrive near each other within the specified limits.
Within alertYou can specify a geo area and if any spatial object comes in to the specified area an alert will be generated.
Stationery alert You can specify a geo area and a fluctuation radius and a time, which will generate an alert if any spatial object is located in that area during the specified time. Fluctuation radius is used to minimize the fluctuation effect of a spatial object.
Congestion AlertYou can define a geo area. An alert is generated when the congestion level in that area changes.
