Hydrographic Surveying

SurvTech performs hydrographic surveys on rivers, lakes, quarries, berths, and coastal water bodies, using the latest hydrographic technology. With hydrographic survey offices in Mississippi, Mobile, Alabama and, New Orleans, Louisiana we are poised to quickly deploy to your project site in Southeastern United States.

SurvTech specializes in performing hydrographic surveys in logistically difficult environments, including those with difficult access and/or acidic water conditions. Using innovative methods, we have equipped a one-manned vessel, unmanned vessel, and an amphibious vessel with survey equipment to access areas that cannot be surveyed by traditional means.


With these innovative methods we regularly perform surveys where others say it's impossible. With the sonar technology listed below, we can map underwater conditions in high definition, as well as map below the seafloor to find utilities and geologic formations.

Hydrographic Surveying Methods

Hydrographic data collection can be combined with mobile laser scanning to collect elevations both above and below water level. Positional data is collected with RTK GNSS for centimeter accuracy.
