  • In this paper we present a data migration method for developing GIS-based Fisheries Resources Information Systems after considering standardization of existing methods and analyzing characteristics of such systems. First, a strategy for data migration is defined. Second, a iterative process to build a spatial database is planned. Third, the process is executed to make database transformations and basic data are converted into real GIS data. Finally, developers and users cross-check data correctness. As a result of our research, we suggest a data migration method for GIS data and confirm its usefulness by applying it to real projects.

  • The 3-dimensional GIS data provider system manages and retrieves 2, 3-dimensional spatial and time data. This system provides the standard interfaces which help developers to omit additional works to do modify or convert a format of 2 or 3-dimensional spatial data, which has been already accumulated, into that dependent on a specified system. This system consists of a data provider and data access component. The former deals with the connections with some databases and manages the meta data, so that the various GIS or software can access to 3-dimensional spatial and time data via the same method, and the latter takes charge of index management and spatial operations on GIS data for consumers. The system offers the diverse spatial operations and analysis functions for 3-dimensional GIS.

  • Since building up the Geographic Information System actively, we doubt whether we make good use of those system. These problems are caused by that legacy GIS is focused on the information construction and management of various facilities. So raising up the usability of GIS, we study on the GIS based on KMS that is active developed recently. First, we discuss about the concept of KMS and make the method to develop KMS with related to GIS. Then we make up the pilot system(g-KMS) according to the method for using on the filed of Construction. Consequently, we make sure that Spatial information is so important among various knowledges and find the why how to spatial knowledge build up.

  • As the networks proliferate all over the world and the application of the geographical information increase recently, the importance of effective access and exchange of GIS data is recognized. However, existing GIS data are generated by many different organizations without proper standard methodologies and data exchange facilities such as clearing houses are being operated on different DBMS with their own schemata. It makes difficult for users to access and utilize the GIS data even the data are open to public. In this research, we provide the users a search system that interfaces heterogeneous repository systems. In order to interact heterogeneous DBMS we utilize the metadata interchange standard (XMI) from OMG.

  • This paper briefly describes the classification of GIS- based model, and introduces some practical grid- based models such as TOPMODEL (Beven of al., 1979, 1984), AGNPS (Young of al., 1989), KIMSTORM (Kim, 1998; Kim of al,, 1998), and GRISMORM (Kim of al.,20110). Current status of GIS data construction promoted by Ministry of Construction and Transportation (MOCT) and system development of water resources information by Korea Water Resources Corporation (KOWACO) is briefly described. Further research needs for GIS-based modeling will be emphasized with some recommendations on GIS data preparation and proper field observation data collection.

  • The latest system of GIS has been changing from 2 dimension to 3 dimension. According to the rapid growth of the fields linked to 3D GIS, 3D GIS has variously affected the public field, the national defense field. and the industrial field. This study estimated sight distance safety of curve section considering the environmental impact based on 3D GIS. Sight distance is calculated from the relation between road which keeps the three-dimension character and driver gaze, so it needs to consider both plane and vertical for the accurate measuring. This study made analysis of the sight distance through considering the environmental impact with driving simulation of design speed 80km/h and running speed 60-120km/h.

  • It is necessary to construct an effective regional information system in facing the incoming information intensive society. Many local government in Korea began to recognize a need for constructing a GIS(Geographic Information System) and they are planning to construct GIS´s to improve their administrative efficiency. However, ti requires high-priced hardware, software, and an experienced operator to sue a GIS effectively. The purpose of this study is to develop the GIS program which can be sued with ease by common users. By developing a GIS functioned program using a coordinate recognition module by application of geo-spatial data, and a digital map which is already made, this program can be used efficiently only by only inputting attributes without high-priced hardware and software, and can be utilized easily to every purposes of work with geo-spatial data and attributes. MapObjects, mapping and GIS component, was employed to use geo-spatial data, and Access 97 from Microsoft to manage and attributes database. Visual Basic, objected-oriented language, was used to develop an application program. Results of this study were applied to constructing the Information system of Kanwon National University. This program could be used for various purposed by common users without additional hardware and software.

  • Road traffic-related environment problems has become now serious problem common in the urban life throughout the world. In this study, a GIS-supported evaluation system has been developed for dealing with the road traffic-related environment problems, especially focusing on air Pollution in the urban areas. The developed system consists lof three essential parts: GIS; traffic-related air pollution simulation model; and the database for potential strategies. In establishing the simulation model, a GIS-supported environment can provide a useful tool for handling a wide range of data characterizing study areas and for preparing more accurate estimation on real locations. Such roles of the GIS-supported system can be helpful to more efficient analysis and more reasonable decision-makings. As a preliminary stage in developing the system, the metropolitan area of Cairo in Egypt was applying into being as a Pilot study to test the Potentiality of the prototype system.

  • At a turning point of new paradigm, each countries in the world are try to search solutions to a current problems of the times in maritime than land. In special, as a maritime power that KOREA is surrounded by the sea on three sides, our country place more weight on maritime. To accomplish a powerful maritime power, it is necessary to create a digital marine spatial on the basis of Marine and Coastal GIS. This planning is establishing that our country, to construct a systematic, efficient Marine and Coastal GIS Infrastructures, is to analyze the present state of internal & external, law and planning related in Marine and Coastal GIS, and establish vision, mission, core values, goals, strategies by setting a basic concept of Marine GIS
