약도는 지도와는 달리 특정 목적지까지의 중요한 요점으로 지리정보를 표시하므로 웹 사이트 상에서의 지리정보 제공에 더욱 효율적이다. 약도는 거의 모든 웹 사이트에서 1개 이상 게재되고 있을 만큼 보편적인데 반해 이용자 입장에서의 요구조사가 불충분하다. 따라서 본 연구에서는 현실감을 높이기 위한 약도 제공의 방법으로 Interactive 3D 약도를 제안하고 약도 제작자와 이용자 입장에서의 요구 조사를 통하여 실제로 활용이 가능한 웹 기반의 3D 약도 제작 시스템 프로토타입을 제안하였다. 웹 3D 약도를 웹 상에서 제작하고 이용함으로써 제작자에게는 펀리함을, 이용자에게는 효율적인 정보 습득을 가능하게 하고 나아가 웹 3D 약도가 보편화될 수 있는 가능성을 제시하였다.
The need for online geographic information and sharing has increased in line with the development of the internet. A sketch map, unlike a map, which provides detailed information on broad areas, identifies important destination and is provided in most websites in order to give guidance to company location, branch location, and venue of event. However, web master faces difficulties in producing more detailed and realistic sketch maps; as such most sketch maps are provided in the form of 2D graphics. Therefore, this study aims to develop a system, which can make 3D modeling of sketch maps to increase the degree of the sense of the real. This will be a convenient and effective system to both designers of sketch maps and web users by analyzing the work process differentiated by varying perspectives of designers of sketch maps and web users and by designing a system interface which nicely blends these different perspectives. Researchers collected web-provided sketch maps and extracted special features and indispensable elements. They also observed the process of drawing sketch maps and determined the drawing steps through analytical tools. 3D sketch map producing system makes the sketch maps convenient to edit and delete by converting them to zip files and save database. In particular, designers of sketch maps added process indicator functions in line with a diverse spectrum of communication means, which may go unnoticed by designers of sketch maps. Website designers can easily put various elements such as roads, buildings, and viaducts into sketch map modeling online and post them on the website. Sketch map users can use this system to view sketch maps of 3D modeling and at the same time acquire lively information in a cyber environment through interactions such as expansion, reduction, rotation, and shift.
