How much does a hydrographic survey cost?

Average survey costs are estimated at R 500-650/day or R 1.000/ km 2 (~US 250/day or ~US 400/km 2 ), depending on boat ownership vs. rental cost. This represents less than 1/10 of the official traditional survey costs, and even less when compared to LIDAR bathymetry.

What is shoreline survey?

In sea shore survey, buoys anchored off the shore and light houses are used as reference points and are located by triangulation.

How is bathymetry measured?

Today, echo sounders are used to make bathymetric measurements. An echo sounder sends out a sound pulse from a ship’s hull, or bottom, to the ocean floor. The sound wave bounces back to the ship. The time it takes for the pulse to leave and return to the ship determines the topography of the seafloor.
