SYSTEM AND METHOD FOR LOCATING, TRACKING, AND/OR MONITORING THE STATUS OF PERSONNEL AND/OR ASSETS BOTH INDOORS AND OUTDOORS
First Claim
1. A computer-implemented method of tracking a trackee both indoors and outdoors, comprising:
- receiving as input, at a computer, tracking data for a trackee, wherein the tracking data includes tracking points, and wherein each tracking point includes at least two-dimensional location coordinates;
correlating the tracking data to building or sensor data features to improve the accuracy of the tracking data if building data has been received, by the computer, as input;
generating, in the absence of received building data, features of a building based on the tracking data; and
displaying, via a graphical user interface associated with the computer, position estimates generated based on the tracking data.

Abstract
A system and method for locating, tracking, and/or monitoring the status of personnel and/or assets (“trackees”), both indoors and outdoors, is provided. Tracking data obtained from various sources utilizing any number of tracking methods may be provided as input to a mapping application. The mapping application generates position estimates for trackees using a suite of mapping tools to make corrections to the tracking data. The mapping application further uses information from building data, when available, to enhance position estimates. Indoor tracking methods including, sensor fusion methods, map matching methods, and map building methods may be implemented to take tracking data from one or more trackees and compute a more accurate tracking estimate for each trackee. Outdoor tracking methods may be implemented to enhance outdoor tracking data by combining tracking estimates such as inertial tracks with magnetic data, compass data, and/or with GPS, if and when available.
