3차원 지적공간 구축을 위한 지목분류체계 개선방안

3차원 토지 이용을 반영하도록 지목 분류체계 개선 방안을 연구했다.

Today's land use becomes diversified and three-dimensional under the effect of fixation and non-expansion in urban concentration of population and geographical position of lands. Our nation registers land categories such as principle of one-purpose-per-one-land, principle of following-main-land-purpose, principle of importance-use, and so on, which cannot reflect lands used complexly on land and underground and is not identified to the practical land use situation.

To solve above issues and introduce three-dimensional cadastral land system, three-dimensional cadastral land system giving land categories to not only land sign but also vertical spaces, ground facilities such as highway, ground railroad, apartment, and transmission tower, underground buildings such as subway, underground warehouse, underground parking lots, etc, and underground facilities such as electricity, communication, gas, etc is needed to be introduced.

Thus, the thesis studied issues of the current two-dimensional cadastral land and the need of three-dimensional cadastral land Also, through classification of land use by each institution, analysis of cadastral land situation of our nation, situation of foreign cadastral land classification system, and survey and analysis on hand-on workers handling cadastral land information, cadastral land classification system was organized as hierarchical structure in three detail classifications of large, middle, and small classification to reflect three-dimensional land use situation and it was departmentalized to index land registration, ground land registration, underground land registration, and so on.
