1. A method comprising:
retrieving a previous representation representing a target portion of a space;
obtaining a current representation representing the target portion of the space;
comparing the previous representation to the current representation to identify a change in the target portion of the space;
mapping the target portion of the space to a three-dimensional (3D) representation of the space to locate the change within the 3D representation; and
storing a change map defining the change in context of the 3D representation.
