Abstract

In this paper, the effective convergence methodology of spatial data for establishing 3-Dimensional model on the basis of cadastral concept and state-of-the-art surveying techniques were proposed, and also the possibility of its sharing with diverse fields was suggested. The original data which were observed through Terrestrial Laser Scanner(TLS), Airborne Lidar, Mobile Mapping System(MMS), Terrestrial Photogrammetry, Multi Looking Aerial Photogrammetry, which are introduced as one of the latest surveying methods, were compared with the coordinates of check-points from Total station(T/S). As a result of evaluation from TLS and MMS, it was satisfied with their tolerance, that is, the horizontal location error in numeric areas(0.1m) and the standard deviation of altitude point(0.15m). In case of Airborne Lidar, the vertical error were satisfied but horizontal location ones not. Building model created by cadastral survey was suitable for the resolution of outer wall's location and shape, but the data of building's roof could not be created. On the other hand, in case of building model on the basis of Aerial Photogrammetry, the resolution of building roof's shape was satisfied but its location and shape of outer wall were not. Moreover, in order to be satisfied with the precision of location and format based on cadastral surveys, four optimal convergence models which are consisting of a TLS on the basis of land surveying, building outer wall model created with terrestrial photometry surveying, Airborne LiDAR surveying a roof model create by a multi looking aerial photogrammetry, were proposed for the utilization of various fields.
