Abstract

Recently, the utilization of geospatial open platforms has been constantly increased and the interest in 3D geospatial data such as terrain, building and shopping mall has been increased significantly. In particular, rather than simplified 3D geospatial data, interest in high-precision 3D geospatial data which similarly represents the real world objects has increased significantly. In order to satisfy the demand for such the high-precision 3D geospatial data, various kinds of 3D geospatial open platforms has been developed and has provided services on the web. However, most of the 3D geospatial open platforms have been used plug-in module in order to ensure a fast 3D rendering performance on the web, despite the many problems such as difficulty of the installation, no supporting of cross browser/operating system and security issues. In addition, recently, the existing 3D geospatial open platforms based on plug-in module are facing a serious problem, by declaring the NPAPI service interruption in Chrome and Firefox browsers. In this study, we presents the design and implementation of a new 3D geospatial open platform based on HTML5/WebGL technology without the use of plug-ins. Such the new 3D geospatial open platform based on HTML5/WebGL may support cross browsers such as IE, Chrome, Firefox, Safari and cross OS platforms such as Windows, Linux, Mac and mobile OS platforms.

최근 공간정보 오픈플랫폼의 활용도가 지속적으로 증가하고 있으며, 지형, 건물, 쇼핑몰 등과 같이 3차원 공간정보에 대한 관심이 크게 증가하고 있다. 특히, 단순화된 3차원 공간정보가 아니라 실세계와 유사한 고정밀 공간정보에 대한 관심이 크게 증가하고 있다. 이러한 3차원 공간정보에 대한 수요를 충족시키기 위하여 다양한 3차원 공간정보 오픈플랫폼들이 개발되어 서비스를 제공하여 왔다. 그러나, 대부분의 3차원 공간정보 오픈플랫폼들은 빠른 렌더링 성능을 제공하기 위하여 설치 과정의 어려움, 크로스 웹 브라우저/운영체제 지원 불가, 보안 약화 등의 많은 문제점에도 불구하고, 플러그인 모듈을 부득이하게 이용하고 있다. 더구나, 최근 크롬, 파이어폭스 등의 웹 브라우저에서 플러그인 모듈의 동작을 지원하였던 NPAPI 서비스에 대한 중단을 선언함으로써, 기존 플러그인 기반 3차원 공간정보 오픈플랫폼의 동작에 큰 문제가 발생하게 되었다. 이에 본 연구에서는 플러그인을 사용하지 않고 3차원 공간정보를 빠른 성능으로 서비스할 수 있는 방법으로 HTML5/WebGL의 차세대 웹 표준 기술을 활용한 새로운 3차원 공간정보 오픈플랫폼의 설계 및 구현 방법을 제시하고 있다. 이러한 HTML5/WebGL 기반의 차세대 공간정보 오픈플랫폼은 Windows, Linux, Mac 등의 크로스 운영체제와 IE, Chrome, Firefox, Safari 등의 크로스 브라우저, 그리고 모바일 플랫폼에서 동작이 가능하다.
