Abstract
Recently, the Ministry of Land, Infrastructure, Transport and Tourism (MLIT) has been using Construction Information Modelling/ Management (CIM) in its construction projects. CIM has the notion of using a 3D model in the life cycle of construction phases such as planning, design, construction, and maintenance. By sharing the models in each phase, the ideal of CIM can be anticipated. With this idea in mind, the use of 3D data in the design phase has substantially improved the construction process. Thus, in order to apply the use of 3D data in road maintenance, road surface point cloud data is acquired using mobile mapping system (MMS). In previous research, the authors have applied the use of point cloud data in the design and construction phases by analysing their attributes. In this study, the authors have defined the importance of assigning attributes to point cloud data and proposed the way to assign the attributes. As an example, the authors have applied this proposal in Town A, which is a vast amount of point cloud data derived from MMS in order to accomplish the road surface data management.
