A system receives a vehicle data snapshot. The system compares characteristics of the vehicle data snapshot to a database of known characteristics, the known characteristics identifying one or more instances corresponding to an instance type identified in a geo-fence request, the instance types in the geo-fence request having been submitted for geo-fencing around occurrences of instances of the instance type. Responsive to identifying an existence of an instance at a location where the vehicle data snapshot was taken, based on the comparison, the system establishes a geo-fence around the identified instance and transmits the established geo-fence to one or more vehicles associated with the geo-fence request.
