Abstract

Recently, in the area where cadastral resurvey project was completed, a variety of information is offered through the newly registered cadastral record using parcel survey such as the decision of parcel boundary and building boundary. This research presented the way that the real boundary of architecture such as the roof and eaves is registered in the tentatively named building boundary monument record as the form of pictures by using Drone at the area of cadastral resurvey project. The study analyzed the position accuracy of the building bounding in the result map of cadastral resurvey and drone orthophoto. According to the analyzed result between the boundary of the roof and eaves and ground building boundary by overlaying orthophoto produced by Drone with building boundary of the result maps of the cadastral resurvey, position accuracy shows that RMSE is 0.832m as X, 0.809m as Y. In the case of county farming villages as the target area of the cadastral resurvey project, there are a lot of differences between boundary of roof, eaves and ground boundary of building because of the many detached houses of Hanok style. Furthermore, this phenomenon should be registered in the record and managed. Therefore, this survey suggests the recording plan called building boundary monument record. It also provides the possible method to confirm the roof boundary and eaves without the cadastral surveying after cadastral resurvey project is completed.
