1. A method of mapping a machine having a work tool, comprising: sensing an outer boundary of the machine and generating a first set of information indicative of the outer boundary of the machine; moving the work tool relative to the machine through substantially an entire range of motion of the work tool; sensing an outer boundary of the work tool during movement of the work tool through substantially the entire range of motion and generating a second set of information indicative of a location of the outer boundary of the work tool through substantially the entire range of motion; determining information indicative of a position of an object disposed proximate the machine; and determining whether the information indicative of the position of the object is included in either the first or second sets of information.
