Abstract: Imaging, attribution, and 3D modeling of utility pipelines and other assets is accomplished through the processing of terrestrial photogrammetric, aerial photogrammetric, and/or 3D LiDAR scanning measurements, all of which may be augmented by an Inertial Measurement Unit. These measurements are spatially controlled by photo-identifiable targets whose positions are established by real-time or post-processed GPS measurements which, in turn, determine the relative and absolute positions of the resulting 3D model. The necessary attribute information is available the moment an optically readable code is affixed to the asset. All proposed data collection methods provide imagery and point clouds systematically. It is therefore possible to read the attributes encoded in the optically readable code directly from the imagery or point cloud. Both the attributes of the feature and the position of the encoded attributes on the feature are captured.
