  • Recently as users' requests for geographic information systems are being more various, several new functions are being added to existing geographic information systems. One of them is linkage of spatial geographic data and video / image data to offer more realistic information of geographic objects to users. Geographic information systems implementing this function are called video geographic information system. In this paper, we design and implement a video geographic information system for providing map data, video data and link information of them to web applications. We 1) design system architecture of a video geographic information system, 2) analyze some processes to construct link information of map data and video data, 3) design database schema to store map data, video data, and link information, and 4) design some XML/GML schema used to query and retrieve these data for web applications.

  • Recently, as the geographic information system (GIS) which searches, manages geographic information is used more widely, there is more requests for some systems which can search and display more actual and realistic information. As a response to these requests, the video geographic information system which connects video data obtained by using cameras and geographic information as it is by displaying the obtained video data is being more popular. However, because most existing video geographic information systems consider video data as an attribute of geographic information or use simple one-way links from geographic information to video data to connect video data with geographic information, they support only displaying video data through searching geographic information. In this paper, we design and implement a video geographic information system which connects video data with geographic information and supports hi-directional search; searching geographic information through searching video data and searching video data through searching geographic information. To do this, we 1) propose an ER data model to represent connection information related to video data, geographic information, 2) propose a process to extract and to construct connection information from video data and geographic information, 3) show a component based system architecture to organize the video geographic information system.

  • Geographic Information Systems (GIS) is considered to be one of the most important technologies provided by the Internet in our era. GIS enables institutions and individuals to plan and make decisions in many fields. GIS assists in accessing new and updated information on planning process. GIS also enables determining distances such as length, width, area on a map, and allows analyzing and processing a large amount of data for the search of geographical characteristics of locations. This paper explains the concept of dispensing prescription through the specific code of drug on an electronic system using GIS technology. The proposed methodology aims to inform patients of all the prescriptions dispensed and to help individuals inquiring about prescription at the nearest pharmacy through GIS technology. This proposed methodology is considered significant in some cases, as the patient does not know price, specifications and pharmacy location where the drug required is available, thus increasing the time and effort cost that is spent searching for the prescription.

  • In Korea, the railway history has more than 100 years and the KTX(Korean Express Railway) was launched on April 1, 2004. Nevertheless, the safety management of the railway has not been emphasized. Thus this paper proposed the novel frame of the railway safety management system which can secure the railway safety and administer the railway accidents via Management Systems from domestic to international. Secondly, we developed the prototype Management System for the railway accident based on GIS(Geographic Information System) by introducing the concept of "location". This Management System has two parts: space and attribute. Also it provides the map for emergency actions.

  • Today, satellite remote sensing and geographic information systems plays an important role as a advanced science and technology, and becomes a superpower tool of the study and research in various fields of Earth Science. This study reviews the application of satellite remote sensing and geographic information systems for many specialists in the fields of the fishery and ocean science. In future, satellite remote sensing and geographic information systems will be greatly used to observed, monitor and predict various phenomena associated with the fisheries and oceans, in order to seek safety in a natural disaster, and menage and conserve the fisheries and resources and the oceanic environments.

  • GIS can be used on almost entire fields of the world, such as the national land management, environmental management, disaster management, enterprise activities, and general lives. GIS is called as an infrastructure of the knowledge information on the cultural society. For insuring the national power on the periods of the unlimited competition, it is very important to establish the national information infrastructure. Purpose of the NGIS project I is to development on living benefits of peoplethrough an efficiency of policy and rationalism of planning. In order to achievement of this purpose, the NGIS project I has been established using the national geographic information base planning. The NGIS project I consists of the master management part, the geographic information part, the technique development part, the standardization part, and the land Information part. These five GIS project parts are operated by four governmental ministers and related institutions, such as minister of transportation and construction, minister of science and technology, minister of information and communication, minister of administrative and home affaires. The NGIS I project is to establishment of the nation spatial information systems, such as various nationwide digital maps, GIS technique development, GIS education, GIS standardization, and GIS researches.

  • The temporal GIS data modeling methods are discussed in this paper. At first, two conceptual models of spatio-temporal data are introduced, and then some typical STDMs based on these two models are summed up and compared. After that, the spatio-temporal changes are analyzed thoroughly, and then how to model spatio -temporal data from different aspects is discussed. At last, several issues that need further research are pointed out.

  • The objective of the paper is to recommend a database format of geographic informa¬tion systems for transportation (GIS-T) based on a review of geographic data files (GDF), a European standard format for navigation and the topologically integrated geographic encoding and referenc¬ing files (TIGER) if the USA The establishment of the standard format for transportation database is important for sharing data since data collection is costly. We believe the recommended format would reduce the implementation costs for GIS-T in Korea in the future.
