1. A system, comprising:
ultra-wideband (UWB) tags located for association with respective objects in an environment, each UWB tag identified with a digital label indicative of the association with one or more of the objects; and
a tracking service implemented at least partially in hardware and configured to:
receive initial location data for the one or more objects as global positioning system (GPS) data;
generate an object identity database, each of the one or more objects identified by their respective initial location data;
receive subsequent positioning data for the one or more objects from each of the UWB tags that are associated with the one or more objects; and
monitor for movement of an object based on a change of positioning of the object from an initial position indicated by the initial location data to a subsequent position indicated by the subsequent positioning data.
