Individual culture information has been the mainstream in studies on culture information so far, and the studies have focused on zones using paper map. As a result, intuitive analysis in map and extremely restricted measuring space analysis are limited in summarizing and utilizing complicated and huge cultural materials systematically and scientifically. Introduction of GIS can be regarded as an indispensable element for solution of this problem as it can analyze temporal-spatial dynamics of culture information as a whole and to construct effective management system for regional culture information. In particular, supply of two-way information rather than one-way information becomes more and more important in the society structure where value is diversified and the culture gets faster owing to high-level information industry like today. Accordingly, this study is considered to be meaningful in that WebGIS-based regional culture information system allows temporal-spatial analysis and spatial analysis for various culture information for the users using internet. Regional culture information system like culture information system in Honam region can not only contribute to comparative study between regions and to creation of new information through analysis of statistics between culture elements but also allow easy and comprehensive approach to regional information.

Although the railroad industry has progressed in terms of amount and quality because of the opening of the new express ways in 2004 and the construction and openings of the express railroads of cities, the establishment of safety has been poor so there has been lurking accidents and it resulted in big accidents like a Daegu subway fire. Therefore, this study is to minimize damages of life and property by establishing GIS, a map for emergency and Activity-Action and emergency reaction scenario through a web in case of emergencies mentioned before.

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.

High resolution satellite imagery is regarded as one of the important data sets to engineering application, as well as conventional scientific application. However, despite this general view, there are a few target applications using this information. In this study, the possibility for the future wide uses in associated with smart graphics of this information is investigated. The concept of smart graphics can be termed intelligent graphics with XML-based structure and knowledge related to semantic web, which is a useful component for the data dissemination framework model in a multi-layered web-based application. In the first step in this study, high resolution imagery is transformed to GML (Geographic Markup Language)-based structure with attribute schema and geo-references. In the second, this information is linked with GIS data sets, and this fused data set is represented in the X3D (eXtensible 3D), ISO-based web 3D graphic standard, with styling attributes, in the next stop. The main advantages of this approach using GML and X3D are the flourished representations of a source data according to user/clients’ needs and structured 3D visualization linked with other XML-based application. As for the demonstration of this scheme, 3D urban modelling case with actual data sets is presented.

Recently, web services concept is rapidly rising as new solution to solve the integration problem among heterogeneous application systems . This web servic es concept is adaptable in the field of 4S application systems integration that handles the spatial information of GIS, SIIS, GNSS and ITS. So, this paper suggests a new 4S web services model for the infrastructures of nationwide spatial clearinghouse, which is mainly based on the OGC and W3C web services specifications. Conclusively, this proposed model that could serve various spatial data and services has some advantages of being flexibly and powerfully capable of integrating the 4S application systems owing to adapting the international standard specifications of OGC and W3C.

The author argues that the current Government Information System for river water quality appears to be non-user friendly due to lack of the cartographic representation for the field monitoring data. Acknowledging these constraints, an operational, user-friendly information system has been developed by combining Internet technology with GIS. A digital map for water quality has been generated by overlaying monitoring data on existing cartographic data such as road, topography and administrative boundary etc. A user interface was designed to address the need to querry the large spatial databases by non-GIS and non-environmental experts. The system has been checked experimentally and enabled the users to querry data required simply. And detailed visual maps for water quality can be generated over large areas quickly and easily. A visual mapping system for water quality was developed by reframing the monitoring data as graphic symbols and it was ideally suited to exploring area-wide water quality at a user-friendly manner due to extensibility and scalability along the various survey points. This system based on Web GIS could be accessed anywhere if internet is available. It would play a crucial role in improving the quality of public information service if it is operationally introduced into the Government since the highly user-friendly interface provides a completely new means for disseminating information far water pollution in a visual and interactive manner to the general public.

최근 들어 한국철도기술연구원 (KRRI) 에서는 자동운행이 가능한 바이모달 트램 시스템을 개발하고 있다. 이 바이모달 트램 시스템은 노선에 설치된 센서를 자동으로 인식하여 자동 운행을 하며, 재해 발생시 수동으로 운행될 수도 있다. 바이모달 트램 시스템이 노선에 설치된 센서를 인식하여 자동운행을 하기 때문에, 기후패턴 변화에 따른 집중강우로 인해 예기치 않은 홍수 발생시 바이모달 트램 시스템 승객 및 차량의 안전이 확보되어야 한다. 따라서 본 연구에서는 Web GIS 기반의 트램 재해관리 시스템 (Bi-modal Tram Disaster Management System: BTDMS) 프로토타입 버전을 개발하였다. 이 BTDMS 시스템은 US EPA에서 개발한 SWMM 모험을 핵심 엔진으로 활용하여 지표면 유출 및 관거 해석을 수행한다. 본 연구에서는 기상청 예측 강우량 자료를 이용하여 실시간 내수침수 예측을 수행할 수 있는 모듈, 지표면 유출수의 흐름을 고려할 수 있는 모듈, 그리고 지역별로 유출심을 산정하여 바이모달 트램 시스템 운행 판단의 기준자료로 활용할 수 있는 모듈을 개발하여 BTDMS에 추가하였다. 이러한 모듈을 이용하여 예측된 자료는 바이모달 트램 시스템의 운행 속도를 늦추거나 우회노선을 선택하는데 활용될 수 있을 것이다. 본 연구에서 개발한 Web GIS 기반의 BTDMS는 2009년 상반기 밀양 지역에 설치될 바이모달 트램 시범지역에 적용되어 그 적용성이 평가될 것이다.

Web on Web 2.0 paradigm is regarded as a kind of platform. Accordingly, users on web can use almost same applications like using certain applications on personal computer, to given purposes. For Web as platform, it needs web-based or web-recognizable file format to communicate or to exchange various information contents and data among applied applications. Text-based JSON is a practical format directly linked Javascript on Web, so that XML-typed data, being previously built, can be possible for tagging process containing JSON format. However, GeoJSON handling geo-spatial data sets is now fledgling stage in standards. Thus, it is not on the practical applicability level, and there are a few tools or open sources for this format. To adopt GeoJSON for the future Geo-web application, users implement GeoJSON parser or apply the server-based open source GIS for their purpose. In this study, a preliminary work for GeoJSON application in Geo-web service carried out using Google Maps API and openlayers library API.

It is important to scrutinize spatial patterns in crime analysis since crime data has geographical attribute in itself. We focus on the development of ¨Crime Analysis GIS¨ prototype which can discover spatial patterns in crime data by integrating mapping functions of GIS and spatial analysis techniques. The structure of this system involves integration of DBMS and GIS, and the major functions of the system include (i) exploring spatial distribution of point data, (ii) mapping hot-spot, (iii) clustering analysis of crime occurrence, and (iv) analyzing aggregated areal data. The process of design and implementation of this system is based on object-oriented methodologies. A web-based extension of the prototype using 3-tier architecture is currently under development.
