Abstract

There are various structures in the underground space, and the structures is managed as 3D data in Integrated Underground Geospatial Map Management System(IUGMMS). The worker transmits and updates the integrated map including the changed underground geospatial data to IUGMMS with the completed book submission program. However, there is a problem in that the transmission time and the update time is delayed because the size of the integrated map file is large. In this paper, we try to extract and transmit only the changed integrated map by obtaining and comparing each spatial characteristic information of the integrated map. As a result of the experiment, the transmission time of the suggestion method is short and the update time is also short than the transitional method because the suggestion method transmits only the integrated map including the changed underground geospatial data. As a result, it was possible to reduce the delay time in transmitting and updating the changed integrated map.

지하공간에는 다양한 구조물들이 있고 그 구조물들의 지하공간 데이터는 지하공간통합지도 관리 시스템(IUGMMS)에서 3D 데이터로 관리되고 있다. 작업자는 준공도서 제출 프로그램으로 변경된 지하공간 데이터를 반영한 통합지도 전체를 IUGMMS에 전송하여 갱신하고 있다. 그러나 통합지도 파일의 크기가 크기 때문에 전송하고 갱신하는 시간이 지연되는 문제점이 있다. 본 논문에서는 변경된 통합지도와 IUGMMS에 저장되어 있는 통합지도에서 공간특성정보를 각각 구하고 비교해서 변경된 지하정보 데이터가 있는 통합지도만 추출하여 전송하고자 한다. 실험 결과, 기존 방법은 전송하려는 통합지도의 영역이 넓을수록 통합지도를 전송하는 시간과 갱신하는 시간이 파일 크기에 비례하여 증가하였지만, 제안한 방법은 변경된 지하공간 데이터가 포함된 통합지도만 전송하기 때문에 전송 시간이 짧았고 갱신하는 시간도 짧았다. 그 결과 변경된 통합지도를 전송하고 갱신할 때 발생하는 시간의 지연을 줄일 수 있었다.
