In this paper, the design of URL structures and managements for UFID(Unique feature Identification) based wireless communications is presented with the combination of GIS and URL address informations. As a result of IPv6 based UFID wireless communications, new methods for URI(Uniform Resource Identifier) informations and UFID communication systems are proposed with a 6byte coded 128-bit IPv6 DNS system for the presentation of 1,500,000 korean buildings.

A Unique Feature Identifier(UFID) is a way of referring to a feature, generally representing a tangible feature in the real world. In other words, a UFID uniquely identifies the related feature in the database and is normally used to link two or more databases together. This paper presents a UFID system aiming at the internal uses for National Geography Institute(NGI) as well as external uses for National Geographic Information System(NGIS) generally to link datasets together. The advantage of the proposed type of UFID lies in the meaningful nature of the identifier in providing a direct spatial index - administrative area and feature code. The checksum character proposed in this research is designed to remove any uncertainty about the number being corrupt. It will account lot digit transposition during manual input as well as corruption in transfer or processing.

The current Digital map is ambiguous to be managed because that's managed partition unit file-based. It brings about the cost of consumption because area has been changed or not is managed redundantly and there has been no way to provide digital map of spatial and time management. In addition, digital map can't have the management of security assurance and systematization because it is managed file-based. Therefore, this research provides figures that after applying UFID per object, it can be managed history every update of it by object unit.

일부 지형지물에 대한 기본지리정보의 생산과 향후 생산될 다양한 지형지물에 대한 기본 지리정보 구축은 국가지리정보체계(NGIS)사업에서 기 구축된 수치지형도의 구조화 및 체계화의 결과라고 할 수 있다. 본 연구에서는 향후 다양한 분야에 사용될 기본지리정보(Framework Data)의 내용을 분석하고, 기본지리정보의 갱신에 있어서, UFID프로세스를 이용한 보다 신속 정확한 기본지리정보의 갱신방안에 대하여 연구하였다.

After 1995, as a part of national geographic information system project, there are a lot of researches about combinations and connections of national geographic information system. However, systematic standard for combinations and connections of geographic information is uncertain, and each organization has different identification system which leads to difficulties in connection of geographic information system. This study suggests repeating method about geographic information objects to grant UFID based on national standards of geographic information system, and analyzes the repeating rate.

정보화 기술의 발전과 더불어 GIS의 대중화에 따라, 다양한 형태와 주제로 공간 정보를 제공하는 수치지도의 수요가 증가하고 있다. 기존의 수치지도 데이터는 도엽 단위로 관리하기 때문에 관리 및 갱신을 효율적으로 지원하기 어렵다. 이 논문에서는 이러한 문제를 해결하기 위해 객체의 연속적인 표현, 객체 단위의 갱신 및 이력관리가 가능한 UFID기반의 수치지도 데이터 모델을 제안하였다. 제안한 모델은 각 지형지물에 새로운 UFID를 부여하여 연속적인 지형지물 표현과 갱신으로 인한 지형지물별 이력 관리가 가능하도록 하였다. 마지막으로 제안된 모델의 효율성을 검증하기 위하여 타당성을 분석하였다.

As the results of the information project, manufacturing of the digital map and various thematic maps of the national land has been completed. Furthermore, it is necessary to organize a systemized management system, which can control and utilize all artificial features (e.g. buildings, roads, bridges etc.) as well as natural geographic features (e.g. rivers etc). Howener, it has difficulties in managing NGIS as a unified system, because of the discordance of DB of each geographic management organizations. Therefore, this study has been conducted to apply to the system and method providing geographic UFID that can be a key in order to managing, searching and utilizing geographic and artificial features and that makes it be able to estimate the location with the only identifier. Moreover, the system and method, providing geographic UFID, applies to systemized management of NGIS DB as well as consistency of information.

Nowadays, the importance of safety monitoring for facilities is increasing. Therefore, the introduction of ubiquitous technology to replace the existing manually-operated methods is required. In this study, a web-based GIS system that provides monitoring information of bridges in real-time for the application of a bridge management system through the use of ubiquitous technology is constructed. Particular attention is given to the effective interconnection of bridge monitoring information and bridge management system and, through a ubiquitous environment, how to connect this with the UFID and the GIS-based bridge management system (BMS) operated by the Ministry of Construction and Transportation. In addition, data expression methods are also suggested that state the detailed locations and attributes of structures in bridge management by using GIS.

The existing facility management system is capable of managing two-dimensional and three-dimensional models that were driven from maps and registered documents. However, it is not capable to collect various fields data on a real time and operate the integrated systems. To supplement those obstacles, constructing a facility management system based on ubiquitous environment is needed. Therefore, this research has proposed the modified UFID(Unique Feature IDentifier), which is more suitable for the facility management by modifying management agency and serial codes system in the existing UFID. In addition, we established the procedures for ubiquitous environment based on facility management using proposed UFID. The feasibility of this research was assessed through case study focused on roadside trees. It is considered that the results can be applied to many other ubiquitous environments based on facility management.

The study aims to secure an integrated UFID system-based ID system as it defines the three-dimensional land registration record through selection and standardization of objects. By comparing the integrated ID system secured by the study and the objected ID system proposed by Seoul City, the study came up with practicality of the integrated ID system for the three-dimensional land registration record information system. An integrated UFID-based intellectual spacial information which is consisted of 41 figures in total was developed by the study. The study confirmed the practicality of the integrated ID system by comparing it with the objected ID of the three dimensional land registration record information system established by Seoul City.
