A Study on Three-Dimension Land Boundary Range Establishment and Public Announcement Method

Abstract

The purpose of this study is to establish the spatial range of three-dimensional land boundary which is increasingly demanded as land use evolves toward ever increasing heights and cubic dimension, and to propose efficient public announcement methods on such basis. The research result has shown that three-dimensional land boundary, as a cubic land boundary, may be viewed as land boundary that includes not only ground surface but also above ground and basement space. First off, to establish ground boundary range, there needs be system that can register the result of cadastral measurement in public record book cubically by performing measurement of cadastral information beyond the existing land registration of ground surface. Establishment of underground boundary range required cadastral measurement which considered the values of height(gap between floors) between ground surface and underground space detailed survey and analysis of various rights issues established on underground space. Therefore, to accurately map out the boundary of underground space and above ground space and to efficiently publicly announce such information, it was necessary to review applicable legal matters that contain various provisions on the use of underground and above ground space etc. Also, specific and clarified range establishment criteria were required, and input work of accurate graphic information and attributes information was shown necessary to follow. In particular, it was shown required to pursue efficient programs to cubically register land boundary by revising Cadastral Act; the base law stipulating various registration issues on one single parcel, or by establishing separate special law(hereinafter referred to as “Act on cubic Space Information”).
