Claim:
1. A computer implemented method, comprising: obtaining, from a first global positioning system (GPS) device, origin point global coordinates of a global coordinate system for an origin point associated with a physical enclosure; obtaining, from a second GPS device, reference point global coordinates of the global coordinate system for a reference point associated with the physical enclosure, the reference point different than the origin point; determining a first axis of a local coordinate system associated with the physical enclosure, the first axis extending from the origin point; determining an azimuth gamma from a directional reference line to the first axis, the directional reference line extending in a known direction from the origin point at the origin point global coordinates, the determining an azimuth gamma comprising: determining an azimuth alpha from the directional reference line to a given point line connecting the origin point at the origin point global coordinates to a given point within the physical enclosure, the determining an azimuth alpha comprising: determining given point global coordinates of the global coordinate system for the given point based upon the azimuth alpha and a given point line length of the given point line; and determining a physical position of an object within the physical enclosure based upon the given point global coordinates of the global coordinate system; and displaying, through a user interface on a mobile device, the object at the physical position within a digital representation of the physical enclosure.
