Hydrographic surveying is highly specific and requires a suite of advanced acquisition and positioning sensors attached to a mobile survey platform as well as sophisticated software to allow the correct combination of all the data.
When it comes to data acquisition, hydrographic surveyors have always first and foremost been involved in bathymetric data. Collect data relating to bodies of water, and may include the water depth, bottom contours and configuration, directions and velocity of current, heights and water stages, and the location of fixed objects for navigational purposes
Electra uses multibeam echo sounder to conduct hydrographic surveys. Multibeam sonar measures the depth of the sea floor by analyzing the time it takes for sound waves to travel from a boat to the sea floor and back.
