Abstract
Augmented reality (AR) is based on supplementing the view of the physical world with a computer-generated content such as text, images videos, sound, 3D objects etc. The proliferation of smart mobile devices and their high computational capabilities combined with the possibility of GIS 3D visualization and interaction have enabled new kinds of mobile applications. AR is considered as an efficient technology for the underground utilities management. Damages to underground utility lines are considered as one of the major urban problems because incidents caused by unsafe digging practices can compromise community safety and disconnect people from vital services. A prospective study was conducted to identify examples and characteristics of each type of augmented reality. This paper summarizes researches about the types of AR and discuss how this technology could help in underground utilities repairing and maintenance. We present a new mobile location based augmented reality system using smart device sensors and the Real Time Kinematic (RTK) satellite navigation technology of ORPHEON network for the location accuracy. This system enables GIS data visualization to help field workers in outdoor maintenance of underground infrastructures.

The marker should be kept in front of the camera, once the marker is recognized by the camera frame, a virtual computer-generated content can be viewed on a screen and digital assets are placed into the scene at the location of the markers [6] (Figure 2)
The management of underground utilities constitutes a major urban concern. It constitutes an important component of the Smart City
Summary
Cities face a multitude of challenges, because of the fast growth of the population. Underground utilities that provide drinking water, electric power, sewage, and telecommunications, among other services have been gradually added leading to complex subsurface problems. With the digital revolution, advanced systems for integrated management of buried networks could be used. These systems offer the possibility to conduct collaborative work for the design, construction and management of urban underground utilities. Augmented Reality (AR) constitutes a powerful tool for this requirement, because it provides both an integrated 3D view of the geospatial models and immediate feedback to users. It acts in an intuitive way for data capturing, data correction and surveying. It provides classification of the AR types, presents some examples of AR uses in underground networks and proposes a novel AR system for the underground utilities management
