“…The unseen network of UUI is very complex in any urban environment [4]. Their importance and utility infrastructure cadastre would not be obvious until hazards and problems arise, such as a gas explosion, road collapse due to subsurface wash-out, water leakage and seepage to the road surface, etc [4][5][6][7].…”

Application of Kinematic GPR-TPS Model with High 3D Georeference Accuracy for Underground Utility Infrastructure Mapping: A Case Study from Urban Sites in Celje, Slovenia

This paper describes in detail the applicability of the developed ground-penetrating radar (GPR) model with a kinematic GPR and self-tracking (robotic) terrestrial positioning system (TPS) surveying setup (GPR-TPS model) for the acquisition, processing and visualisation of underground utility infrastructure (UUI) in a real urban environment. The integration of GPR with TPS can significantly improve the accuracy of UUI positioning in a real urban environment by means of efficient control of GPR trajectories. Two areas in the urban part of Celje in Slovenia were chosen. The accuracy of the kinematic GPR-TPS model was analysed by comparing the three-dimensional (3D) position of UUI given as reference values (true 3D position) from the officially consolidated cadastre of utility infrastructure in the Republic of Slovenia and those obtained by the GPR-TPS method. To determine the reference 3D position of the GPR antenna and UUI, the same positional and height geodetic network was used. Small unmanned aerial vehicles (UAV) were used for recording to provide a better spatial display of the results of UUI obtained with the GPR-TPS method. As demonstrated by the results, the kinematic GPR-TPS model for data acquisition can achieve an accuracy of fewer than 15 centimetres in a real urban environment.

“…Selection of the ground penetrating radar (GPR) in this paper was carried out after considering its characteristics as a non-destructive method to detect layouts and characteristics of metallic and non-metallic pipe materials. Additionally, this method allows the recognition of other characteristics of WSSs, such as water leaks (Ayala-Cabrera et al, 2013b).…”

In this paper, a ground penetrating radar (GPR) is used as a non-destructive method to assess the buried elements of water supply systems (WSSs). The aim is the detection of various pipe materials (such as plastic and metallic, among others), and the identification of other important aspects (e.g. water leakage). This work seeks to use the visualization advantages of the subsoil characteristics provided by pre-processed GPR images. These features, which are represented as anomalies into the images, are extracted and merged to generate 3D models. The 3D representations obtained facilitate elucidation by personnel non-highly skilful in the interpretation of data from non-destructive techniques. The work is performed on GPR images of WSS pipes taken from strategic locations of urban environments. The goal is to promote the use of these technologies in the WSSs intended to generate relevant information that allows the adequate and dynamic technical management of these systems. The results and analyses are presented in this paper.
