In this study, the marine environment is measured and analyzed in real time through the X-band radar installed on the rooftop of the Sokcho Beach administrative Welfare Center and Ulleungdo. Afterwards, the goal is to transmit the analysis results to the client PC. Using electronic maps and electronic navigational charts, the measurement results are overlaid on GIS (spatial information system), real-time data are shared through a website, and information is displayed through a web server. Currently, CCTV information and marine environment information are displayed on the website, but various application studies such as the use of Open AP I will be conducted in the future.

Many of the wells which were constructed to use ground water resource are abandoned and not managed efficiently after its use. And a variety of heavy metals and organic compounds are released from the abandoned wells and this can cause ground water pollution. Therefore in this paper implemented to monitor locational information drill holes and underground water sensing information on real time basis using u-GIS environment to combined ubiquitous sensor node and GIS technology to improve these problems. In addition, this system suggests using system by UML 2.0 by analyzing variety requirement of user and between system internal modules interaction and data flow. It provides graphical user interfaces (GUI) to system users to monitor water-well related property information and its managements for each water-well at remote site by variety platform by GIS map and web environment and mobile device based on smart phone.

This study, as a pilot study to implement and extend the marine healing which has been rapidly extending oversea areas into the domestic market, has collected seven major marine healing resources such as ocean water, sand, salt, mud, seaweeds, forest, and weather targeting selected four pilot municipalities and established a GIS DB. Furthermore, web GIS based marine healing portal has been established to support the easier utilization of the GIS DB and various marine healing related contents, thereby facilitating expansion of related industry. The portal includes marine thematic maps as well as research papers, related therapy manuals, and various activities and programs of the pilot municipalities. It is expected that the portal would contribute to the expansion of the domestic marine healing industry significantly through the pilot operation of the portal, not to mention of the needs of subsequent studies for expansion of the marine GIS DB and securing more various contents.

Considering constantly increasing number of internet users and information-oriented society with high speed internet network, the application of computer technology is considered to be valuable in urban planning. Particularly, since using Geographic Information System (GIS) is expected to be the best method to convey the information related to the urban planning. Therefore, this study aims at the development of participation system by using GIS and Internet. The system consists of Basic Module, Disposal Module and Decision Support Module. Each module is designed for expressing planning information and processing database, opinion statement and convenience of citizens, and the effectiveness of administration process and decision making. These are connected each other in a basic and simple form, i.e. Java Script and HTML, and the system was realized through data process, Map date and PostGIS for Mapping, and PHP. Last but not least, this system has been tested on the internet and the result indicated its convenience and availability in actual use concluding that participation system has enough application value on urban planning process.

Geospatial information data came recently in use to build the location-based service in various fields. These data were shown via a 2-D map in the past but now can be viewed as a 3-D map due to the dramatic evolution of IT technology, thus improving efficiency and raising practicality to a greater extent by providing a more realistic visualization of the field. In addition, many previous GIS applications have been provided under desktop environment, limiting access from remote sites and reducing its approachability for less experienced users. The latest trend offers service with web-based environment, providing efficient sharing of data to all users, both unknown and specific internal users. Therefore, real-time information sensors that have been installed on steep slopes are to be integrated with 3-D geospatial information in this study. It is also to be developed with web-based environment to improve usage and access. There are three steps taken to establish this system: firstly, a 3-D GIS database and 3-D terrain with higher resolution aerial photos and DEM (Digital Elevation Model) have been built; secondly, a system architecture was proposed to integrate real-time sensor information data with 3D Web-based GIS; thirdly, the system has been constructed for Gangwon Province as a test bed to verify the applicability.

Mobile office is becoming common as advances in mobile devices such as PDAs, Smart-phones, or wireless Internet. In this paper, we construct a mobile office environment on a geotechnical information system(GIS). Especially, web services and XML technology combined with SOA (service oriented services) are adopted for various types of mobile devices and services in a minimum cost. Web service and XML can provide an excellent SW reusability, extensibility, and interoperability even for heterogeneous distributed systems. Applications can exploit web services by just knowing server's address. Prototype system integrates a client in Visual Basic.Net and server in Java via the web services and XML data exchange. We verify effectiveness of the approach through the implementation of prototype system.

본 논문은 농작물 작황 정보의 의미를 보다 정확하게 이해하고 조작할 수 있도록 메타데이타를 정의하는 시멘틱스에 기반하여 정보를 검색하고, 사용자가 작황지역의 위치와 작물 특성을 제공함으로써 더 많은 정보를 획득하는 WebGIS기법을 제시하고자 한다. 그리고 이 논문은 작황정보를 WebGIS와 융합함으로써 위치정보를 획득할 수 있는 작황 정보 시스템을 구현하고자 한다. 사용자가 요청한 질의를 분석, 질의에 일치하는 정확한 지리정보를 제시하고 해당 지리정보와 연계되는 검색결과 서비스를 제공하고자 한다. 그래서 이 논문은 의미 기반 WebGIS정보를 시각화할 수 있는 시스템을 개발함으로써 편의성을 제공할 수 있다.

지리정보시스템은 이미 우리 생황의 많은 분야에서 활용되고 있으며, 점차 그 활용 범위가 확대되어 가고 있다. 이러한 지리정보시스템을 WWW 환경에서 구축함으로써 웹 브라우저만 있으면 누구나 쉽게 지리정보시스템을 접할 수 있게 되었다. 본 논문에서는 지리정보시스템과 같이 많은 데이터를 처리하기에는 속도상의 문제가 발생할 수 있기 때문에, 이를 해결하기 위한 방법으로 Client/Server 설계, GIS-Engine 설계, 위치 검색 시스템 설계, 수직 분할 구조의 설계 등 Web 기반의 지리정보시스템의 설계 기법을 고찰해 보고, 이들 설계 기법을 이용한 관광지리정보시스템을 설계해 보았다. 앞으로 계속된 연구를 통하여 이를 구현하여 Web-GIS를 관광분야에 활용할 수 있도록 할 것이며, Web-GIS가 단지 지리정보의 검색시스템으로 한정하지 않고 응용 범위를 확대하여 다양한 분야에서 활용될 수 있도록 노력하겠다.

Digital photogrammetry workstations are usually based on independent systems which are both expensive and complex. In this paper, through Web Processing Service, which is an Open Geospatial Consortium standard for GIS, is applied to suggest a new approach for processing photogrammetry tasks. WPS profiling is a procedure that defines generic unit process and then categorizes these processes for a specific task. The WPS profile for aerial photogrammetry was designed in this paper to help users to reuse the processes of the profile in different combinations for different tasks.

식물의 생육지에 대한 정보는 여러 연구 분야에서 유용하게 사용될 수 있다. 특히, 생육지의 정보 중 서식지의 위치에 대한 정보는 식물의 특성을 분석하고, 분포나 통계에 널리 이용되기도 한다. 본 연구에서는, 식물의 서식지 정보에 대해 GIS 기법을 이용하여 식물별로 지도상에 표시하고 분포를 확인할 수 있는 생태 정보 시스템을 개발하였다. 남한지역의 수생식물을 대상으로 GIS 좌표정보를 바탕으로 시스템을 구축하였으며, 채집정보가 입력되면 좌표값을 바탕으로 지도상에 자동으로 표시하였다. 근접지역의 채집정보가 누적이 되면 화면상에 중첩되어 표시되는 문제를 해결하기 위해. '동전쌓기방식'이라는 새로운 알고리즘을 개발하여 사용하였다. 또한, 지역에 대한 상세한 브라우징을 위해 확대/축소 및 위치 이동을 통해 생태 정보를 자세히 볼 수 있는 기능을 가지고 있다.
