Abstract

Methods, apparatus and systems for computer-aided determination of quality assessment for locate and marking operations. In one example, a quality assessment decision is solely under the discretion of a human reviewer, albeit facilitated in some respects by computer-aided display of information, and electronic record keeping and communication functions associated with the quality assessment result(s). In another example, information related to a locate and marking operation is electronically analyzed such that a quality assessment is not based solely on human discretion, but rather based at least in part on some predetermined criteria and/or metrics that facilitate an automated determination of quality assessment.
