In u-GIS environments, a geographic information service system for mobile phone is consumer(user) oriented service system based on existing GIS and LBS considering characteristic of mobile phone. In the past, development of a geographic information service system for mobile phone dependent on various hardware specification of mobile phones and mobile operators. From now on, the geographic information service system for mobile phone independents on hardware specification of mobile phones and mobile operators. Also, it changes from service oriented GIS provider(specialist) to service oriented consumer. For the satisfaction of this requirement, we propose a design of geographic information service system for mobile phone using FLEX for creates standard execution file. The standard execution file is able to apply various mobile phone. And we propose a management method of picture contents combination of location information that geographic information service system for mobile phone is provided it firstly. In this system, it provides facilities that display map, manage location, manage contents, manage mash-up, manage map data. And then it provide facility of swf generation for display result map on mobile phone. In this paper, we are implemented the proposed system and seen same results in various mobile phone. The created *.swf file provides same result at any time, anywhere, anyone in spite of different zoom level and different display screen.

Over the past few years, a number of studies have been made on web map services which enable the GIS user to access spatial data through the web. They, however. have focused on only implementation techniques separately, such at map client implementation map server implementation, communication between client and server, and the map data representation. Therefore, it is hard to share and practical use the spatial data, because they does not ensure interoperability in heterogeneous map servers. In this paper, In this paper, we have designed and implemented the web map server with open architecture. which complies with the standard interfaces proposed by OpenGIS Consortium (OGC). In particular, we have extended the OGC's Interfaces for a map server to support one or more data sources. This paper has contributed to construction and practical use of web map services by newly proposing the method of implementation of a map server. which could be reused regardless of the types of data sources.

In ubiquitous geographic information environment, the users are provided with geographic information anywhere and any time on their needs by any types of devices and communication media. The unique location ID, ePosition, is a new technology to support UBGI environment, using a logical location ID instead of physical location of a point of interest. Domain names of plural ePosition servers, where location information with its ePosition is stored, needs to be registered in DNS for some service through Internet. For better ePosition service of the type of public service like email service, a set of DNS resource records can be newly defined. This paper suggests a new DNS resource record EPO for implementation of the ePosition service through Internet.

Web Map Service on mobile environment, provided with cost effective mobile GIS contents and user preferred POIs(Points of interests), is strongly required at this moment when mobile and portable Internet is rapidly spreaded on mobile user community as information technology and mobile HW are evolved in its speed, bandwidth and features. As the mobile and portable Internet becomes popular in mobile services, LBS(Location Based Service) is positioned on a mobile client as one of the best information infra services. Recently mobile GIS (Geographic Information System) comes in service to support LBS, but it is constrained and limited on its system configuration and its presentation methodology of a map, and also it depends on its run time environment. In this paper, we made an effort to design and implement a GIS computing platform with server based thin client for mobile WMS(Web Map Service). For its cost effective Platform which could be easily building up POIs and GIS contents, we're not using commercial GIS solution but NGII's (National Geographic Information Institute's) DXF numerical map, and representing the maps, GIS contents and POIs by SVG(Scalable Vector Graphics) recommended by OGC(OpenGis Consortium). We're also adapting de facto standard of XML web service technology such as WSDL, SOAP to provide real time mobile GIS service on PDA as well as mobile terminal by applying a GPS receiver for a user's location information on mobile environment.

Recently, many WMS(Web Map Services) and POI(Point of Interest) services come to be in service on the Internet using Web GIS(Geographic Information System) as Information Technology and computer H/W are evolved faster in its speed, network bandwidth and features. The Web GIS is, however, limited and constrained on the specification of its system configuration, the service class provided and the presentation methodology of a map. As the mobile Internet becomes popular in mobile service, Web GIS service on mobile environment is strongly required and to be provided by location based WMS(Web Map Service) on a mobile client such as PDA with location information of the user. In this paper, we made an effort to design and implement a GIS computing environment by thin client for mobile web map service. For implementing the thin client GIS computing environment. we were using NGII's(National Geographic Information Institute's) DXF map, representing the map by SVG(Scalable Vector Graphics) recommended by OGC(OpenGis Consortium), and adapting standard XML web service to provide the thin client GIS service on PDA by applying the location information of the user in realtime with GPS on mobile environment.

해양 분야에서는 최근 e-navigation 실현을 위한 차세대 표준에 관한 연구가 진행 중이다. IHO(국제수로기구)를 중심으로 전자해도뿐만 아니라 해양의 지리 정보 및 관련 데이터의 교환, 공유, 활용을 위해 S-100기반 다양한 표준이 가능하다. IHO S-100 표준은 ISO 19100 시리즈 표준의 프로파일로, 응용 분야와 서비스에 따른 S-10x 표준의 기반이 된다. 프로파일링을 통해 S-101, S-102, S-10x 등 다양한 표준 프로파일이 만들어지면 각 표준에서 정의하는 데이터 모델의 요소를 일관성 있고 명확하게 해석하는 것이 필요하다. 본 논문에서는 S-10x 표준의 기반이 되는 S-100 표준을 일관된 의미 해석과 처리를 할 수 있도록 S-100 표준의 온톨로지로의 변환 방안을 제시한다.

Recently the integration and development of ST(Spatial Technology) and forest geographic information have been used very efficiently for the forest administration. However, even though many application system related to forest information have been developed and improved, there are still paper based inventories management and hand work for data construction and upgrade. In this study the forest information warehouse, which is mapped and managed at work-site operations, was constructed based GIS technology so that the standardization and consistency of current data could be acquired in real time. In addition, these thematic maps were conducted on high resolution satellite images and managed in web based forest information data warehouse form and finally shared through Internet for the very first-line administration officials. This study shows that the forest information standardization service of municipal governments very first time in the Korea and provides the unified decision making support and enterprise formed forest database so that is expected to be the very successful sample to suggest the prototype of national forest spatial data infrastructure.

기존에는 이질적인 GIS 데이타 소스간의 통합을 위해 랩퍼(wrapper)기술을 사용했다. 랩퍼(wrapper)는 외부 클라이언트 응용프로그램에게 이질적인 데이타 소스들의 통합 데이타 모델을 제공함으로써 데이타와 지리정보처리의 공유를 가능하게 한다. 그러나 데이타 소스들의 통합은 표준 서비스를 포함한 상호운용성을 지원하는 것은 아니다. 표준을 따르는 상호운용을 위해서는 표준화된 데이타 모델과 서비스가 필요한데 OGC (OpenGIS Consortium)의 OpenGIS(Open Geodata Interoperability Specification)가 이를 제공하고 있다. 분산환경에서 상호운용을 위한 기존방법은 각 데이타 소스별로 데이타 제공자를 개발하여 상호운용을 지원하였다. 따라서 중복 구현에 대한 문제와 구현에 따른 노력과 비용이 상당 부분 존재하였다. 본 논문에서는 데이타 제공자에서 공통부분을 추출 및 컴포넌트 화하고 데이타 소스에 종속되는 모듈은 CORBA 구현객체로 작성하여 제시하였다. 따라서 각 데이타 소스들은 표준 데이타 제공자를 통해서 기존의 데이타 지원 기능유지와 상호운용성을 달성할 수 있다. 클라이언트는 OpenGIS Feature모델을 기반으로 한 표준 인터페이스로 데이타 소스에 접근한다. 데이타 소스는 표준데이타 제공자와 정의된 인터페이스를 바탕으로 CORBA의 구현 객체 서버를 작성함으로서 중복구현 및 구현부담을 줄일 수 있다.
