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 beta from the directional reference line to a reference point line connecting the origin point at the origin point global coordinates to the reference point at the reference point global coordinates based upon the origin point and the reference point;

    determining an angle delta from the first axis to the reference point line; and

    determining the azimuth gamma based upon the azimuth beta and the angle delta;

    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 an angle theta between the first axis and the given point line based upon given point local coordinates of the local coordinate system for the given point; and

    determining the azimuth alpha based upon the angle theta and the azimuth gamma;

    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.
