Geospatial interoperability has been pursued by propagating international standards and OGC standards. The NGIC, GeoConnection and other catalogue services are reviewed with aspect to metadata and search functions. Detailed metadata could be driven to users after finding what they want to have. Criteria for search were not fully overlapped with metadata, as simple and typical searches are prevailing. OGC catalogue service standards were made but catalogue services in Korea have been implemented in their own ways, not fully compliance-tested. Different domain technologies have been developed regardless of geospatial service, the relationship and integration methods between catalogue services and other core technologies are reviewed in the form of a pair table. Other issues in geospatial service were discussed in the level of raising issues.

The basic purpose of standardization is to enhance economic feasibility and increase efficiency in the field of production, consumption, and distribution, etc. Therefore, standardization field requires circulatory system that can not only produce standards but develop and revise published standards. With such a background, to activate standards and promote systematic standardization activities, the government proposed establishing circulatory system for geospatial information standards in the National Geospatial Information Standardization Project in 2011. However, the result of analysis show that the current National Spatial Data Infrastructure(NSDI) standardization system caused a various problems including duplicate publication of standards because domestic NSDI standardization field have repeated production activities of standards without conformity assesment and certification activities. With a view to establishing circulatory standardization system, this study suggests ways of improving current domestic standardization system by reestablishing the cycle structure and circulatory system for geospatial information standards. Through this study, we could determine strategic direction for virtuous circle of geospatial information standards in macro level and it can be effectively utilized in term of planning mid-and-long-term roadmap for establishing NSDI standardization system.

The standardization of NGIS emerges as an important subject because of the needs for sharing information and assuring of information inter-operability. The standardization could be developed by refering OSE/RM, which is promoted internationally, that the corresponding national standards are required. The standardization of NGIS, that has been promoting, consists of standardization of national electronic base-map and common data exchange format. The process for standardization of base-map has been taken in the area of feature-attribute code and data modeling. In the area of common data exchange format, we have been accepted the accommodation of international standards as the national standard.

최근 과학 기술의 발달과 정보화로 인해 다양한 분야의 방대한 정보들이 디지털화되어 저장되고, 이를 효율적으로 저장하고 관리하는 기술에 대한 수요가 증대하고 있다. 특히, 수자원 분야에서도 지점 관측 형태의 직접 계측방식이 아닌 선, 면 형태의 간접 계측방식의 기술이 개발됨에 따라 짧은 시간 동안 많은 수의 양질의 자료를 취득할 수 있게 되었다. 이에 따라 과거에 비해 방대하고 연속적인 하천공간정보가 축척되었으며, 이를 저장하고 관리하고자 하는 필요성이 대두되고 있다. 하천공간정보 중 하천단면자료는 하천기본계획수립 시 핵심이 되는 자료중 하나일 뿐만 아니라 하천의 흐름 특성을 해석하기 위한 여러 물리 모형의 입력 자료로서, 하천의 물이 흐르는 하도공간을 흐름방향의 횡방향으로 절단하였을 때 생기는 면을 기록한 자료이다. 국가에서는 하천단면자료 계측을 위해 많은 예산을 투입하고 있으며, 실제로 많은 수의 하천에서 하천단면자료를 계측하고 있다. 하지만 계측된 하천단면자료는 컴퓨터를 이용하여 제도하는 응용프로그램용 파일(CAD)로 저장되어, 하천단면자료를 지속적으로 저장 관리 모니터링하기에는 어려운 실정이다. 본 연구에서는 이러한 하천단면자료를 지속적으로 저장 관리 모니터링 할 수 있는 시스템 개발을 목적으로 현재 개발 중인 하천공간정보 표준 자료모형과 하천공간정보를 전송할 수 있는 표준자료 전송 언어인 RiverML을 활용하였다. 본 연구에서 도입한 하천공간정보 표준 자료모형은 하천망을 기반으로 한 상호연계를 기본으로 하고 있어, 하천망을 구성하는 각 하천과 해당 하천의 단면자료 간의 관계를 규명하기 쉬우며, RiverML은 이와 유사하게 하천망을 기반으로 다양한 정보를 전달하기 쉬운 전송언어이다. 또한 국가에서 개발한 공간정보 오픈 플랫폼인 브이월드(Vworld)의 API를 활용하여 저장된 하천단면자료를 표출할 수 있게 하였다. 본 연구의 결과는 하천단면자료 저장 관리 모니터링에 유용하게 사용될 수 있을 뿐만 아니라, 지속적인 개발을 통해 하천에서 계측되는 공간정보뿐만 아니라 하천의 시설물, 생태환경, 문화 등의 하천공간정보과 연계하여 효율적인 시스템을 개발할 수 있을 것으로 사료된다.

Signboards are installed in different types and sizes depending on the shop characteristics. However, the local government is having difficulty managing signboards with frequent opening and closing of stores and insufficient management personnel. In this study, a methodology was proposed to standardize and efficiently manage signboard information. To this end, the signboard display method of the enforcement ordinance related to outdoor advertising was analyzed to define the attribute elements of standard signboard data. In addition, physical information of signboards was obtained through signboard recognition technology, which is a prior study, and attribute elements of signboard standard data were defined through information that can be read with the naked eye, building integration information of the Ministry of the Interior and Safety, and street name address. In order to standardize the signboard information by spatial characteristics, data product specifications and metadata were defined according to the national spatial information standard. Lastly, standard data for signboards were produced in XML (Extensible Markup Language) format for compatibility, and XSD (XML Schema Definition) was defined for XML integrity so that data validity could be verified. Through this, a standard data model for the informatization of signboards was designed.

In these days, application cases of national or international standards in the field of geo-spatial information based on information technology are being increased. Especially, demands regarding distribution, dissemination and interoperability of contents using geo-spatial images and these information resources are also on the increasing stage, so that standards as core elements supporting these trends are getting to be emphasized. However, interests on standards of geo-spatial image information processing including remotely sensed images and efforts for development and application of these standards are not enough, domestically. In this study, international standards for geo-spatial image information in ISO and OGC as well as the domestic status were reviewed with the summaries concerned. Comparison with international and domestic standards shows that most national standards were partly modified and translated with international ones, but there are rare cases of application plans or studies concerned in this field. If these situations are continued, industrial stack or applications of technologies regarding standards are getting lesser. Therefore, it is necessary to analyze some problems and to study strategy to overcome them, and the result of this study could be used for the initial works.

In any production and construction of geospatial information covering surveying, survey control point is a vital geospatial information. Survey control points in South Korea are currently classified as following: national control points, public control points, and cadastral control points. Each of these different categories of survey control points act as a basis and sets perimeters for the production, management and operation of subjects within the category. Universal standard, the unified format between different survey control points, also, are not yet defined, causing difference in basic information provided by altering categories and disturbance in connecting, managing, utilizing and operating survey control points. Establishment of a standard regarding survey control points, is therefore required for the efficacy of their utilization. This study, to solve such inadequacies, selects management items for creation of standardized survey control point, by investigating domestically and internationally the status of operating survey control points, determining data model for management, establishing TTA and agency standards, and establishing of activation methodology for survey control point standards.
