ENC기반의 해저수심정보 계측 및 분석 시스템 개발에 관한 연구

Abstract

The data resulted from hydrographical survey are very important for both marine research institute and dredgers. These data include information about depths, tides and currents, quality of the bottom and so on. It is very difficult to get those data easily since the task to get those data costs a great deal of money and efforts.

This study proposed a method to develop a hydrographic survey and analysis system. In order to make the system low-costed, the proposed method includes an electronic navigational chart (ENC) and single-beam echo sounder. ENC is useful tools to display the locations and the soundings of surveyed area, and the single-beam echo sounder was adopted due to its low price and high accuracy characteristics.

This study shows the results of survey carried out by the proposed system, and also verifies its effectiveness in both accuracy and cost.

With the proposed system, there are advantages for users to get and check the submarine topographic data simultaneously. And also the system has several advantages so as that the persons concerned dredging works understand and learn easily how to operate and use the system, how to deal with and how to analyze the surveyed data.
