NTBA has been performing hydrographic surveys since 1992. Currently, we are performing hydrographic surveys under our 5th three year Statewide Hydrographic Survey Retainer Contract for the LaDOTD. Our qualified personnel have completed well over 250 surveys with the methods and equipment required for precise hydrographic surveying. Our hydrographic survey systems are equipped with DGPS receivers and single beam echo sounders.
