Abstract

In this paper, we presented the processing process of the sea floor mapping system using multi-beam echo-sounding data through actual measurements and the results of processing the multi-beam echo-sounding data obtained by exploring some waters of Yeosu Bay. Simultaneously and continuously observe the location and water depth of the sea using GNSS and multi-beam echo sounder, synchronization of the two data, depth correction process considering the tide level at the time of observation, 3D model of the seafloor, contour map, and longitudinal and cross-section data of the seafloor topography. In addition, by extracting efficiently the dredging volume according to the dredging area and planned water depth required for dredging construction management of submarine projects, it can be used for maintenance and management of marine construction sites and ports.

본 논문에서는 실측을 통해 다중빔 음향측심 자료를 이용한 해저면 맵핑 시스템의 처리과정 및 여수만의 일부 해역을 탐사하고 얻어진 다중빔 음향측심 자료를 처리한 결과를 제시하였다. 다중 빔 음향측심 시스템의 검교정 과정, GNSS와 다중빔 음향측심기를 이용한 해상 위치와 수심을 동시에 연속적으로 관측하여 두 데이터 동기화와 관측당시의 조위를 고려한 수심보정 과정을 거쳐 해저 3차원 모델과 등고선도, 해저지형의 종·횡단면 자료 등을 추출하고자 하였다. 또한 해저 프로젝트를 수행함에 있어 준설시공 시 필요한 준설영역과 계획수심 설정에 따른 준설토량을 효율적으로 추출하는 과정을 제시함으로써 해상건설과 항만의 유지관리 등을 위한 자료로 활용할 수 있도록 한다.
