Abstract

대부분의 GIS 서비스들은 단일 어플리케이션에서 동작되어 왔으며, 데이터 처리와 컴퓨터 및 모바일 기술의 급속한 발전에 사용자들은 각각의 GIS 자체 데이터와 이질적인 다른 여러 지리정보시스템의 효율적인 공유를 요구하고 있다. 그러나 많은 GIS 어플리케이션들은 자체 데이터 포맷을 유지하고 있어 상이한 데이터 포맷에 대해서 처리하지 못하며, 모바일 GIS를 위한 필터링 기능이 없는 단점을 가지고 있다. 본 논문에서는 현재 사용되고 있는 지리 정보인 DXF(Drawing eXchange Format), DWG(DraWinG), SHP(SHaPefile) 등의 다양한 포맷이 가지는 특성을 수용하고 지도를 표현하기 위한 핵심 정보를 추출하는 모듈을 설계하며, 통합 뷰에 의해 가시화하여 다양한 포맷의 일관성을 보이며, 모바일 디바이스로의 확장을 위해 추출된 핵심 데이터를 GML로 생성하는 SMP(Synthetic Map Preprocessor)를 설계한다. Most of GIS services have been operated in single applications, and as data processing and computer and mobile technologies have developed rapidly, users request for efficient sharing between each GIS's own data and various different GIS's. However, since many GIS applications maintain their own data formats, they are incapable of processing data formats different with each other, and do not have a filtering function for mobile GIS. This paper designs an integrated preprocessor, SMP to accept features of various current formats of geographic information such as DXF(Drawing eXchange Format), DWG(DraWinG), SHP(SHaPefile), etc., and to extract core information for describing maps. The geographic information extracted by SMP(Synthetic Map Preprocessor) shows consistency in various formats by visualizing through the integrated view. By generating the extracted core data in GML, it supports rapid access to mobile devices and extensibility of file formats overcoming heterogeneity.
