APPARATUS AND METHOD FOR SURVEYING UNDERWATER LANDSCAPES

摘要

An apparatus and a method for surveying underwater landscapes are disclosed. The apparatus for surveying underwater landscapes according to the present invention comprises: a land reference point-establishing portion; a random reference point-establishing portion; a random coordinates-measuring portion; a target location-establishing portion for establishing, as a target location, a location on the ocean floor where an offshore structure is installed; a marine coordinates-measuring portion for measuring marine coordinates including the linear distance and direction from a random reference point established by the random reference point-establishing portion to the target location established by the target location-establishing portion, and a perpendicular distance from sea level; and a marine coordinates-calculating portion for calculating the marine coordinates including a horizontal distance and direction from a land reference point established by the land reference point-establishing portion to the target location established by the target location-establishing portion, and a perpendicular distance from sea level from the sea level, based on random coordinates measured by the random coordinates-measuring portion and the marine coordinates measured by the marine coordinates-measuring portion.
