Abstract

In these days, considering the trend to make various information blended based on spatial information like road, buildings and geography, it is to be very important to visualize maps for showing the information efficiently. However, geometry which is composed with line, polygon commonly used on web service has limitation to express information by limit of usage as well as spending certain time to show the information via map. That's why this study develops the efficient way to visualize huge and complex spatial information. This way is to bring partial space with spatial query, and then query and expand information excluded the former area after detecting movement event based on client. When the way is implemented, it will be expected to make efficient visualization in entire system by not bringing unnecessary information but shortening spending time to show area because it just shows areas which clients want to see.

최근 도로, 건물, 지형과 같은 공간정보를 기반으로 한 다양한 융합정보가 생성됨에 따라 이를 효율적으로 표현할 수 있는 지도의 시각화가 중요하다. 그러나 흔히 사용하는 웹 지도 서비스에서 라인, 폴리곤과 같은 복잡한 포인트로 이루어진 형상정보는 지도를 통해 표출하는데 일정 시간이 소요될 뿐만 아니라 이용할 수 있는 사용제한 기준이 있어 정보를 표현하는데 한계가 있다. 이에 본 연구에서는 용량이 비교적 크고 복잡한 공간정보를 효율적으로 가시화하기 위한 기법을 제안하였다. 이 기법은 공간질의하여 일부영역의 데이터만을 가져오고 클라이언트 기반의 움직임 이벤트를 탐지하여 이전 질의 영역을 제외한 정보를 조회하여 확장해가는 방법이다. 이 기법을 적용했을 때 클라이언트가 원하는 영역만의 정보를 요청하기 때문에 표출에 대한 소요시간을 단축할 수 있으며, 불필요한 정보를 가져오지 않아 전체적인 시스템 측면에서도 효율적인 표출이 이루어질 것으로 기대된다.
