A system and method for generating a one-dimensional spatial index and a temporal index in relation to one or more two-dimensional location points of one or more mobile devices to enable near-real-time searching of devices having fast-changing location information is provided for. The present invention may be used in a variety of implementations including being used in conjunction with searching for mobile devices within a geographical area for a time period; finding nearby devices within a time period; tracking device movement within a time period; determining clusters of devices for identification and location across different geographical regions at once.
