Recently, Construction business is changing from on the ground to underground space because of deficit of developing space, creation of green space and of incremental of land compensation expenses. Meanwhile, 3D Topographic, Marine and Cadastral maps need to have Spatial Interrelation. Also, understanding of the information is also needed. Spatial information object registration system is impossible to contact and understanding intelligence mutually because the former one is managed as automatic ID system. Therefore, 3D Object information ID System of underground space is managed based on Object Identifier. Construction of Spatial information integration ID System is required and it will offer Division Code (Ground, Index, Underground) and depth information. We are defined and classified Under Spatial Information in this paper. Moreover, we developed the integration ID System based on UFID for cadastral information Construction. We supposed underground spatial information DB Construction and a developed the way of exploiting 3D cadastral information system through the study. The research result will be the base data of Standard ID system, DB Construction and system Development of National spatial data which is considered together with spatial interrelation.

The national spatial information systems project which is promoted by our country has been extended from existing 2-D geographic information to 3-D spatial information as the basic geo-spatial Information. Most of the construction of the ground geo-spatial information are completed or underway, on the other hand, the construction of the subsurface geo-spatial information has difficulty caused by the lack of the drilling data characterizing the subsurface. In terms of the construction of the geo-spatial information of the subsurface, the subsurface information is constructed and managed by the domestic institutions, but the subsurface information which is possessed by the institutions was not shared mutually so it is managed inefficiently. This study presented the 3-D national underground information DB design by dividing with the ground DB item which configures the state of the ground and the soil DB item which configures the state of the soil in order to increase the efficiency of the construction of the subsurface spatial information. The implementation & utilization of the national underground information application technology was reviewed by applying the constructed DB to the actual model area, and the national underground information knowledge-based community establishment plan was presented.

공간정보의 처리에는 방대한 양의 자료가 분석되어야 하므로 강력한 컴퓨터 하드웨어와 소프트웨어의 성능이 뒷받침 되지 못했던 80/90년대와 달리 최근에 비약적인 발전을 가져온 분야중의 하나이다. 공간자료구조는 지리정보시스템(GIS)의 핵심엔진으로서 이를 활용한 공간정보의 분석과 처리는 수많은 응용을 갖고 있으며 파생되는 응용분야가 날로 증가하고 있는 추세에 있다. 그러나 대부분의 지리정보는 지상에 대한 것으로서, 지하정보에 대한 연구는 지하정보의 비가시적인 특성상 현재 초기단계라고 할 수 있다. 본 논문은 탄성파를 이용하여 얻어진 지하 지층구조 정보를 분석하여 지층구조를 파악하고, 공간자료구조를 활용하여 지하 단층대를 분석하고 검색하는 시스템 개발 방법을 제안하고 이와 관련된 사항을 기술하였다. 지하 단층대의 확인 작업은 다양한 지상/지하 구조물의 안정성에 중요한 역할을 하는 자료가 된다. 공간자료구조를 활용하여 지하지층을 인식하는 시스템의 개발은 지질 전문가의 해석을 위한 전처리 시스템으로서 중요한 역할을 할 것이다.

Today, the domestic construction area has changed from the ground development area to the underground space development area. In addition, the problems of sprawling development and environmental pollution in the process of developing underground space have become significant. In the circumstances, it is expected that the use of underground space information, which helps to understand underground space, will be on the sharp rise. However, the underground information in Korea is separately established and managed by each institution, and it is difficult to use the information in an integrated way. Therefore, at the time when the information on underground space is integrated, it is required to perform the integrated DB standardization in order to establish the integrated infrastructure of underground space information. In this work, this researcher studied a plan of using the standardization of the integrated infrastructure of underground space information. As a result, this work suggested standardization of each geologic stratum, standardization of unit systems, and standardization of the connection of underground space information regarding the standardization contents of underground space information integration. To examine its availability, this researcher conducted a questionnaire survey with experts of each institution. As a result, the suggested plan was found to be have high availability.

Today, it is difficult to re-use and share spatial information, because of the explosive growth of heterogeneous information and specific characters of spatial information accumulated by diverse local agency. A spatial analysis of subsurface spatial informa-tion, one of the National Spatial Data Infrastructure, needs related spatial information such as, topographical map, geologic map, underground facility map, etc. However, current methods using standard format or spatial datawarehouse cannot consider a se-mantic hetergenity. In this paper, the layered ontology model which consists of generic concept, measuremnt scale, spatial model, and subsurface spatial information has developed. Also, the current ontology building method pertained to human experts is a expensive and time-consuming process. We have developed the MDA-based metamodel(UML Profile) of ontology that can be a easy under-standing and flexiblity of environment change. The semantic quality of devleoped ontology model has evaluated by reasoning engine, Pellet. We expect to improve a semantic sharing, and strengthen capacities for developing GIS experts system using knowledge representation ability of ontology.

The development and utilization of underground spaces are increasing as the use of land based on ground surface became limited due to rapid urbanization triggered by population growth and industrialization. Despite its merit of efficient use of limited land and space, it may contribute to occurrence of various disasters such as sinkholes and damage to underground facilities. After the sinkholes formed and occurred across the country in 2014, there has been an effort to establish Underground Space Integration Map containing 15 types of underground information. Still, there is an increasing demand to improve the quality of underground information stemmed from continuation of such events including the rupture of the hot water pipe in Goyang-si and the fire in the KT site in Ahyeon-dong, Seoul. Hereby, with the aim to improve the quality of Underground Space Integration Map, this study analyzes quality standards, regulations, and guidelines related to spatial data to improve quality inspection standards and methods included in the production rules for the Underground Space Integration Map. In particular, it suggests improvement plan for data quality management for pipe-type underground facilities, known as lifelines, which are essential part of daily life of the citizens, and the largest cause for accidents according to 15 types of underground information managed through the Underground Space Integration Map.

Since the current database systems for managing geotechnical investigation results were limited by being described boring test result in point feature, it has been trouble for using other GIS data. Although there are some studies for spatial characteristics of subsurface modeling, it is rather lack of being interoperable with GIS, considering geotechnical engineering facts. This is reason for difficulty of practical uses. In this study, we has developed subsurface spatial information model through extracting needed geotechnical engineering data from geotechnical information DB. The developed geotechnical information clustering program(GEOCL) has made a cluster of boring formation(and formation ratio), classification of layer, and strength characteristics of subsurface. The interpolation of boring data has been achieved through zonal kriging method in the consideration of spatial distribution of created cluster. Finally, we make a subsurface spatial information model to integrate with digital elevation model, and visualize 3-dimensional model by subsurface spatial information viewing program(SSIVIEW). We expect to strengthen application capacity of developed model in subsurface interpretation and foundation design of construction works.

In line with the modern era in which the safety of underground facilities and the use of underground information are increasingly emphasized, the state is pushing for more precise and accurate underground spatial information to be secured and utilized. Therefore, we need to pay more attention to subsurface geospatial data. In the future, the Ministry of Land, Infrastructure and Transport will actively utilize the 15 types of Integrated Underground Geospatial Information Map(6 types of underground facilities, 6 types of underground structures, 3 types of ground) that the Ministry of Land, Infrastructure and Transport is building as three-dimensional underground spatial information, and contribute greatly to improving national safety and convenience in underground construction. expected to do However, when a site manager requests an Integrated Underground Geospatial Information Map with a mobile device, if the large-capacity integrated underground space map is not quickly transmitted over the wireless section and is not serviced, it causes inconvenience to the site manager and delays work. In this paper, the goal of this paper is to enable field managers to quickly receive a tiled Integrated Underground Geospatial Information Map with minimal information exchange. Therefore, the tiling system is configured according to the dataset for high-speed Mobile Integrated Underground Geospatial Information Map transmission. In addition, a transmission system for the Mobile Integrated Underground Geospatial Information Map is established, and a TCP/IP (Transmission Control Protocol/Internet Protocol)-based spatial information tiling transmission protocol dedicated to the on-site Integrated Underground Geospatial Information Map is developed.
