A method for performing distributed geographic event processing, comprises defining a geographical state system for a universe of locations that includes a model for stateful geographic event processing, said model specifying at least a state transition function for transforming geographic input events into output events and a global aggregation function for aggregating sets of output events, providing a local state system for a subset of said universe of locations being defined as a single-machine implementation of said geographical state system and a local aggregation function being defined as an implementation of the global aggregation function of said geographical state system, and by processing means, creating distributed scalable deployments that implement said geographical state system by dividing said universe of locations geographically among different computational nodes and by instantiating on each of said computational nodes an instance of said local state system and said local aggregation function conforming to the subset of said universe of locations assigned to the respective computational node.
