GIS를 이용한 공간정보의 교육은 이제 선택이 아니라 모든 산업분야에서 폭넓게 채택되고 있는 필수적인 분야이다. 그에 비해 GIS 콘텐츠는 GIS를 하나의 도구를 통해 공부하고자 하는 학생들에 있어 매우 생소한 분야이며, 그 정확한 의미와 학문의 범주를 파악하기가 어렵기 때문에 인터넷을 통해 공간 정보 콘텐츠를 쉽게 접근 하고자하는 의도에서 현재 사용하는 커리큐럼의 분석을 통해 GIS 콘텐츠 기반에서의 공간정보의 적용방안을 제시한 것이다. 그리고 참여자의 관심과 확인을 위해 제천지역의 GIS콘텐츠 사례를 추가적으로 보완하면 더욱 유익한 공간정보교육 사이트로 발전할 수 있을 것으로 기대된다.

This paper proposes a new GeoPhoto contents markup language that can create u-GIS contents by using the spatial photos. GeoPhoto contents markup language has designed the GeoPhoto contents model and markup language for contents that can be used the spatial photos information. GeoPhoto con tents markup language is represented by the convergence of GIS information, location information, photos information respectively. GeoPhoto contents markup language to provide a variety of pictures related to the content model consists of GeoPhoto contents model and operations between the GeoPhoto contents. GeoPh oto contents model supports GeoPhoto model, CubicPhoto model, Photo model and SequenceGeoPhoto mod el. In addition, this paper propose the Annotation operation, Enlargement operation and Overlay operation for represent the GeoPhoto contents. GeoPhoto Contents Markup Language has the advantage of supportin g user custom contents model of u-GIS.

The purpose of this study is to present the role of NGIS(National Geographic Information System) and the development strategy for Business GIS in the ubiquitous society. We analyze the level of GIS technology with the ICT(Information Communication Technology) as well as GIS application trends especially in location-based circumstances. Also, we advocate not only making GIS contents to meet the international standards such as GML(Geography Markup Language) and TPEG(Transport Protocol Experts Group) but applying GIS as a killer application to oncoming diverse ICT areas including LBS(Location -Based Service), Telematics, ITS(Intelligent Transport System), gCRM(geographic Customer Relationship Management), DMB(Digital Multimedia Broadcasting), u(ubiquitous)-City and u-Town. Finally, we build a conceptual Business GIS model based on NGIS for QoS, standardization, R&D, education, and security.

Recently, for the advancement of embedded technology about mobile device, a new kind of service, mash-up is appeared. It is service or application combining multimedia content making tool or device and web-GIS(geographic information system) service in the mobile environment. This service can be ease to use for casual user and can apply in various ways. So, It is served in web 2.0 environment actively. But, in the mashup service, because generated multimedia contents linked with web map are new type of multimedia contents which include user's migration routes in the space such as GPS coordinates. Thus, there are no protection ways for intellectual property created by GIS web-map service users and user's privacy. In this paper, we proposed a location and user information hiding scheme for GIS web-map service. This scheme embeds location and user information into a picture that is taken by camera module on the mobile phone. It is not only protecting way for user's privacy but is also tracing way against illegal photographer who is peeping person through hidden camera. And than, we also realized proposed scheme on the mobile smart phone. For minimizing margin of error about location coordinate value against contents manipulating attacks, GPS information is embedded into chrominance signal of contents considering weight of each digit about binary type of GPS coordinate value. And for tracing illegal photographer, user information such as serial number of mobile phone, phone number and photographing date is embedded into frequency spectrum of contents luminance signal. In the experimental results, we confirmed that the error of extracted information against various image processing attacks is within reliable tolerance. And after file format translation attack, we extracted embedded information from the attacked contents without no damage. Using similarity between extracted one and original templete, we also extracted whole information from damaged chrominance signal of contents by various image processing attacks.

As information technologies are improving, geographical information system (GIS) technologies are also developing rapidly and demands for spatial analysis with GIS are increasing. Particularly, the spatial analyses with GIS researches have been noted rather than general GIS researches. However, most GIS researches focus on space dimension: a density-based clustering method (DBSCAN) or a DBSCAN algorithm using region expressed as Weight (DBSCAN-W) but the importance of rational decision making based on time dimension has been neglected. This study adopts system dynamics in order to put time dimension in GIS-based optimum allocation.

It was investigated to find the concept of the distance teaming, its characteristics and components, and to present successful strategies for the development of the GIS(Geographic Information Systems) programs for the online university. The elements of these successful strategies would be as follows. The models considered for the educational environment and characteristics, relationships between professor and student, community constructions for sharing the educational information, various courses based on the level, and linkages among various GIS programs.

The purpose of this paper is to analyze the implementation of the GIS infrastructure systems for the u-City, GIS base u-City represents spatial information derived fields, such as geographical distribution of the urban boundaries, physical configuration of the urban locations and cultural characteristics of the urban history. These three aspects relate to urban infrastructure systems implementation, urban monitoring center implementation, and spatial database implementation. In terms of the GIS based u-Ci쇼 urban infrastructure implementation systems, the u-City depends on IT contents and spatial features. IT contents are strongly related to IT839 strategy due to the national agenda is "u-Korea". GIS should contribute to u-City construction through the spatial analyses methods. For these methods various GIS functions will guide to u-City's distribution, location, and characteristics of urbanization. The infrastructure consists of road and road facilities, underground facilities, related agencies facilities, dispatch systems, environmental systems, and urban planning. These six units of the urban infrastructures have spatial databases that consist of spatial configuration, such as dots, lines, and polygons in order to draw the spatial distribution of the u-City GIS based u-City urban infrastructure implementation systems should deal with It convergence to generate fusion affects.

The purpose of this paper is to analyze the activation methods of GIS industries through GIS industry current issue analysis in Korea to provide as following. First of an in order to analyse current GIS industries, there are three divisions as follows: existing GIS industry, new technology GIS industry, and commercial GIS industry. The existing GIS industry includes survey industry, municipality UIS and remote sensing. The new technology GIS industry has telematics industry, LiDAR industry, ubiquitous industry, LBS industry, internet, and u-city industry. The commercial GIS industry consists of civilian request GIS industry and spacial data distribution industry. The national geographic information industry contains problems and directions of the 1st, 2nd NGIS and 3rd NGIS plan direction policy. These classified GIS industries present various problems of policies and invaluable results for the future GIS industry activation directions as follows: Presence of the GIS contents technologies win be the most important core for the GIS industry activation related to IT839 policy of the government in Korea.

GIS 콘텐츠의 가장 중요한 대상이 되는 지형 및 지리 공간정보는 다양한 자료의 수집과 변환에 의한 시스템 통합을 통하여 완성된다. 즉 다양한 공간자료의 통일된 표준화에 의해 통합을 이룰 수 있으므로, 그 내용과 형태가 서로 다른 공간정보는 처음 수집된 상태에서 여러 변환 과정을 통해 다른 형태와 영상으로 새롭게 생성되어 통합을 이루는 요소가 될 수 있다는 것이다. 본 연구에서는 대형 댐의 건설로 인하여 수몰된 지역의 과거의 지공간의 정보원 찾아 현실세계와 비교하여 그 차이를 살펴보기 위하여 영상복원을 하는데 이용된 여러 가지의 지공간 자료의 처리과정을 통하여 일반 사진부터 디지털 위성영상자료, 수몰 직전에 제작된 지형도, 마을 사진 등을 통합과정 을 통하여 수몰 이전의 GIS콘텐츠의 공간정보의 통합에 의한 활용 기법을 확인하였다.
