【 摘 要 】

The rapid progress of urbanization around the world has lead to an issue of urban land shortage. As such, the urban infrastructure, especially the utilities infrastructure, were buried underground for space saving and better design of urban landscape. However, this has created difficulties in locating these infrastructures from ground surface since they are invisible to the naked eye. Therefore, this paper offers a method to secure as-built information of the underground utility feature without excavation. This is done by utilizing digital image processing, a series of experiments conducted on preferred test site and real model simulation. By securing these underground utilities as-built information, it can contribute to the sustainability of cities through better urban planning. Moreover, the significant findings achieved in this study also eligible to pinpoint that ground penetrating radar (GPR) backscatter with appropritate treatment can yield unique backscatter signature which functional for identification of the types of underground utility without proving excavation. Thereby, good agreement between the backscatter reflections of GPR with respective underground utility not only serves as input which can channelled into a city's planning, but also uncovers the immense potential of GPR backscatter in reporting the "feature information" of the objects.
