Method for performing distributed geographic event processing and geographic event processing system

A geographic event processing system comprising:

• a geographical state system, the geographical state system including:
• a universe of locations including a plurality of locations,
• a set of states,
• a family of initial states which assigns an initial state to each location in the universe of locations,
• a set of geographic input events, each geographic input event including one or more state transition functions that map, for one or more locations in a support of the respective geographic input event, a current state to a pair of a next state and an output event, and
• a global aggregation function for aggregating sets of output events;
• and
• a processor configured to geographically divide the universe of locations into a plurality of subsets, each subset including one or more locations, and to instruct each of a plurality of computational nodes to instantiate a local state system corresponding to a respective one of the plurality of subsets, each local state system including a local aggregation function conforming to the respective subset of the universe of locations to which the local state system corresponds.
