| 초록 | 연구결과는 다음과 같다. 1. 범용 vector format인 XDF와 MapInfo의 MIF format을 KGIS의 표준 format인 KID로 import, export 할 수 있는 모듈을 개발하였음. 2. 여러 가지 raster image format(PCX, TIFF, JPEG, BMP)을 KID format으로 import, export 할 수 있는 모듈을 개발하였음. 3. Windows 98용 KGIS에서 GIS자료를 입력하고, 처리, 분석, 출력할 수 있는 소프트웨어를 개발했고, 처리 및 분석 기능이 있는 raster-cector editing, topology, raster-vector overlay, slope map, image rectification, classification 및 Ladnsat TM, NOAA, SPOT, IRS 1-C등 위성영상을 처리할 수 있는 기능을 개발하였음. 4. KID DB 포멧에 저장된 자료를 그래픽으로 visualization 할 수 있는 2D, 3D 디스플레이 기법을 개발하여 사용자의 입장에서 사용하기 편리하게 디자인 되었음. 5. 태백지역에 대한 GIS DB 구축(LANDSAT 위성사진, 지질도, 지화학도, 항공 지구물리탐사도, DEM, 3차원 지질도, 3차원 지형도, 음영기복도, 광물 부존가능지역 주제도 등). 6. 1/5만 축척 지질도 전산화 완료. 7. Windows 99용 KGIS를 UNIX workstation용으로의 변환(test version) As the development of computer technologies is growing faster and rapidly, the scope of human's capabilities through extensive use of advanced hardware, software, data base and network. has been enlarged to meet the situation of information society. Especially, due to variety of data is inputted, manipulated and created processed output in different format and to decide mission critical operation, the need to establish systematic management system, DBMS(Data Base Management System), is focused to be a big issue to handle information system past couple of years. Data base is the place where all the information or data are collected, stored in a certain format and makes a link to these data in terms of file system. It also serves as a tool that user can manipulate and create useful report which allows to decide mission-critical decision. The data stored to DBMS is not only text but also graphic, video, audio, movie and they get linked to produce hyper-media report. The Geo-Information produced and published from KIGAM are many different kinds of maps, images, field obtained data, numerically analyzed data and other related data which covers entire territory of Korea. To integrate, retrieve, manage and analyze these spatial data and provide useful information to the researcher as an aid to focus more specific field of work, GIS(Geographic Information System) techniques must be applied as a basic method onto the DBMS. The software required to establish GIS based DBMS consists of GIS utilization package and RDBMS(Relational Data Base Management System). In the next year of this study, the well known GIS package and RDBMS whichare best suitable for our Institute will be purchased and develope software which doesn't support from GIS package but need for our Institute based on the languages supplied through GIS package with parallel to upgrading already developed image processing software. To design standard format for the data which is to be inputted to DBMS, collected data from the advisory staff of each division will be analyzed in advance and, considered characteristics of technical information of work load. The designed standard format will then be applied to pilot area which will be selected with consideration of more interesting and a variety of data previously obtained area. Software to be developed will be mainly focused on the user-friendly GUI(Graphic User Interface) interface on windows and X-windows and modified according to the user's request. During the third year of this study, the developed software package will be ported to the main server computer which will be capable of handling multi-user through connected network and perform extensive test run. At the same time, the data published form KIGAM under standard format will all be inputted to RDBMS from each division. The software package, named KGIS (Kigam Geo-Information System), consists of input, output, conversion, editing, and analysis, image processing, GIS tools and visualization module. Each module is easily ported to other processing and analyzing module to produce enhanced spatial data and final data is then saved as new channel in DBMS. The real time visualization offers the user an interactive trail-and-error method to customize processing method. The result we've achieved through KGIS would be diverse spatial-maps such as geology map, geo-chemical map, airborned geophysical map, 3D geology map, 3D geographical map, and slope map by maximizing image processing and GIS tools. The KGIS would be utilized in many research field in terms of handling spatial data with attributes information for high level decision making process. The further research field would be developing expert system with rich value-added information supported |
