The management model for ground urban facilities based on Ubiquitous technology is proposed to support the u-City projects going on domestically and, reinforce the nation's competitiveness. This research is a part of the Intelligent Urban Facility Management project of the Korean Land Spatialization Group (KGSL). First, this study started from the investigation of existing u-City businesses in order to drive essential components and considerations for the urban facilities management system. Considering the driven conclusions, this study finally proposed the adequate management model of urban facilities for the newest urban environment, u-City.

Integrated Urban Spatial Information Management Platform (USIMP) is defined as an operational environment where technologies for intelligent management of urban facilities are made possible through the integration of diverse technologies such as sensors for ground and underground facilities, middleware technology, wired and wireless network, GIS-USN linkage. To make the integration of these diverse technology possible, it is imperative to have a sound reference model for the platform. This paper provides a standardized reference model for USIMP based on the RM-OPD(Reference Model for Open Distributed Processing) standard.

도시공간정보 통합플랫폼은 도시의 체계적이고 과학적인 관리, 특히 지상 및 지하시설물 관리에 필요한 센서 및 미들웨어 기술, 유무선 네트워크, GIS-USN 연계 등의 요소기술이 집적된 지능형 도시운영 기반환경으로 정의된다. 도시공간정보 통합플랫폼은 상수도, 하수도, 가스, 난방, 송유, 전력, 통신의 7대 지하시설물과 교량, 육교, 터널 등 도시 지상시설물 등 도로기반시설물 관리를 지능화 할 수 있는 기반 환경을 제공하는 역할을 수행해야 한다. 본 연구에서는 지능형 도시공간정보 통합플랫폼 개발을 위해 플랫폼의 비전을 설정하고 개방형 분산처리 레퍼런스 모델(RM-ODP, Reference Model for Open Distributed Processing)의 적용을 통해 개발전략을 도출하였다.

This research dealt with the methodological procedures of ubiquitous sensor networks, applying to urban ground facilities. Recently Korean government established a guide, "u-City IT Infra guide v1.0" when promoting u-City implement projects. This guide conceptually included general processes about u-City mainframe in overall, but its guidance could not lead the detailed procedures and methods for specific ground facility. Therefore, this research proposed the details of the procedure for the intelligence of facilities after reviewing the existing procedures for ubiquitous city. Newly proposed procedure for the intelligence of facilities was consisted of selection of facility and sensors for intelligence, setting a level for intelligence, and suggestion of service model for the selected facility.

지능화된 도시시설물 관리를 위해서는 상하수도, 가스, 난방 등 지하시설물 및 교량, 도로 등 지상시설물에 대한 관리시스템을 유기적으로 연계하고 상호운영성의 기반위에서 통합 운영환경을 제공할 수 있는 '지능형 도시공간정보 플랫폼'이 필요하다. 도시공간정보 플랫폼은 도시내 다양한 센서 단말 등으로부터 정보를 수집하고 이를 모니터링 및 분석하여 도시관리 및 정보제공 서비스를 수행하는 시스템이다. 본 연구에서는 도시공간정보 플랫폼에 대한 사용자 요구사항을 분석하고, 이에 따라 플랫폼을 구성하는 세부기능을 정의하였으며, 이를 종합하여 도시공간정보 플랫폼 모델을 제시하였다.

The adoption of ubiquitous technologies is increasing for the realization of new effective u-City services. u-City is defined as a next-generation informatization city that can innovate a city's various functions, such as improving the welfare of the citizenry, ensuring safety based on systematic urban management, improving the quality of lives, and increasing convenience in city life, by merging cutting-edge information and telecommunication infrastructures and ubiquitous information services with urban space. There is therefore a need to recognize that a successful u-City implementation strategy involves developing the previous UIS into a ubiquitous technology-based UIS and integrating UIS's various urban informations with effective u-City services. In this paper, for UIS-based u-City implementation, the intelligent integration model of urban spatial information based on interoperability is proposed.

Due to the increasing demands on the efficient use of land and the fast growth of construction technologies, human living space is expanded from on the surface to above and under the surface. By recognizing that the current cadastre system based on 2D was not appropriate to reflect the trend, the researchers are interested in a 3D cadastre. This paper proposed the 3D cadastre data model that is appropriate to protect ownership effectively in Korea. The 3D cadastre data model consists of a 3D cadastre feature model and a 3D cadastre geometry model, and the data are produced by a 3D cadastre data structure. A 3D cadastre feature model is based on 3D rights and features derived from case studies. A 3D cadastre geometry model based on ISO19107 Spatial Schema is modified to be good for 3D cadastre in Korea. A 3D cadastre data structure consists of point, line, polygon and solid primitives. This study finally purposes 1) serving and managing land information effectively, 2) creating rights and displaying ranges about infrastructures above and under surface, 3) serving ubiquitous-based geoinformation, 4) adapting ubiquitous-based GIS to urban development, and 5) regulating relationships between rights of land and registration and management systems.
