1. A method of calibrating a digital photographic image of one or more utility structures, comprising the steps ofa) collecting a digitized photographic image of a utility structure,b) collecting low-density LiDAR data and generating sparse three-dimensional point cloud data from said low-density LiDAR data,c) merging the three-dimensional point cloud data with the digital photograph, andd) determining matrices such that each pixel of the digital photograph is associated with a coordinate obtained from the point cloud.
