Abstract
The system provides approximations of a person's location to interested parties wherein the approximations are based upon a detection device's location and inherent inaccuracies related to that detection device. The system can evaluate location information from multiple detectors and approximate the location using and combining that information. The system can provide a confidence level for that determination. The system can also degrade confidence levels assigned to the location as a function of time. Each location can include a hierarchy of subtypes with each subtype including a precision level, the precision level associated with an accuracy level of a detector involved for placing a person within that particular location. When a detector receives location information, the system described herein can traverse through the locations and their associated precision levels to approximate the correct type of location within the hierarchy using the accuracy level of the detector.
