| contents | <p>As the demand on 3D spatial information has increased in South Korea, 3D spatial information services have been provided by the Ministry of Land, Infrastructure and Transport, Seoul City, DaumKakao and other local governments and related companies. In the map-based 3D spatial services, location correction is an important factor that determines the applicability of specific task. Since existing BIM data consists of relative coordinate values, it has been difficult to be interlinked with GIS data which have absolute coordinates. Therefore, this study proposes a location correction method for indoor and outdoor 3D spatial information through the construction of BIM/GIS platform-based modeling data. To do this, a target of the platform testbed was selected and a process of data construction was conducted using three steps to identify a mismatch between the BIM model that deals with indoor spatial information and an orthophoto-based textured 3D model for realistic visualization thereby designing a location correction algorithm. An algorithm that converts relative coordinates into absolute coordinates was implemented to interlink the BIM model data based on relative coordinates and texturing data based on absolute coordinates for a single building to calculate the absolute location of the building first. Then, a second mapping of texturing data over the BIM/GIS platform map was conducted to correct the final location in the 3D model data.</p> |
