Methods and systems for detecting aggregation events

A computer-implemented method, comprising:

• in response to detecting location data for a mobile device based on an internal positioning mechanism of the mobile device, retrieving, by a computing device comprising a processor, a plurality of stored locations from a database based on the location data;
• determining, by the computing device, that the plurality of stored locations is within a predefined distance of an event location, wherein each stored location of the plurality of stored locations is associated with a respective mobile device of a plurality of mobile devices;
• determining, by the computing device, velocity data associated with respective mobile devices of the plurality of mobile devices;
• generating, by the computing device, a filtered plurality of stored locations associated with a first subset of the plurality of mobile devices each having respective velocity data below a defined threshold value by removing, from the plurality of stored locations, one or more respective stored locations associated with a second subset of the plurality of mobile devices each having respective velocity data that exceeds the defined threshold value;
• and
• in response to determining that a threshold number of the filtered plurality of stored locations is within the predefined distance, generating, by the computing device, a virtual perimeter for the event location based on the filtered plurality of stored locations.

A computer program product, stored on a non-transitory computer readable medium, comprising instructions that when executed by one or more computers cause the one or more computers to:

• in response to detecting location data for a mobile device based on an internal positioning mechanism of the mobile device, retrieve a plurality of stored locations from a database based on the location data;
• determine that the plurality of stored locations is within a predefined distance of an event location, wherein each stored location of the plurality of stored locations is associated with a respective mobile device of a plurality of mobile devices;
• determine velocity data associated with respective mobile devices of the plurality of mobile devices;
• generate a filtered plurality of stored locations associated with a first subset of the plurality of mobile devices each having respective velocity data below a defined threshold value by removing, from the plurality of stored locations, one or more respective stored locations associated with a second subset of the plurality of mobile devices each having respective velocity data that exceeds the defined threshold value;
• and
• in response to determining that a threshold number of the filtered plurality of stored locations is within the predefined distance, generate a virtual perimeter for the event location based on the filtered plurality of stored locations.
