Recently, the research on constructing 3D indoor spatial data has been performed while the interests in 3D indoor space have increased. The 3D indoor spatial data has been constructed based on a variety of raw data such as CAD data, BIM model data and laser scanning data. However, the constructed data is not consistent because the standard of raw data is insufficient. To use the constructed data is difficult to exchange and achieve interoperability between the indoor spatial data. In this study, we have studied on criteria elements of standardization for as-built drawing which is one of the raw data for consistent data modeling of 3D indoor spatial data.
