Technologies
TerraSond's knowledge and ability to manage new technologies enables us to play a key role in the surveying and mapping industry.
We own and maintain a large suite of complex software and equipment that is necessary for executing accurate land and hydrographic surveying and mapping. The technology includes specialized tools for obtaining measurements and performing calculations on land and water that are essential for creating, editing and analyzing spatial and attribute data.
We support our staff's ability to manage new technologies by providing additional education and training. We also encourage hands-on experience to increase the conceptual understanding of geographic information systems (GIS) and their practical application for our projects.
Multibeam Sonar Systems
TerraSond performs more multibeam surveys than singlebeam when measured by staff hours, revenue, data volume or any other measure. TerraSond owns several multibeam systems and regularly rents additional systems when needed. Trained personnel, software, hardware, custom vessels and multibeam echosounder systems in-house allow the fielding of several multibeam surveys simultaneously. Three or more concurrent multibeam surveys are regularly fielded.
Multibeam systems produce high-resolution bathymetry data throughout the survey area.
A multibeam sonar system provides fanshaped coverage of the seafloor with the output data in the form of depths. The system will measure and record the time for the acoustic signal to travel from the transmitter (transducer) to the seafloor (or object) and back to the receiver. Search patterns usually are run as a series of parallel lines that ensure overlapping coverage of the multibeam sonar.
Odom ES3
The ES3-M integrates multibeam sonar with motion sensors resulting in a system with virtually zero fixed offsets (roll and pitch), meaning quicker installations, faster calibrations and reduced setup errors. 
Reson SeaBat 7125
The SeaBat 7125 is a single and / or dual frequency (200/400kHz) multibeam echosounder system ideal for a great variety of hydrographic, offshore, military, bathymetric, side scan & snippets applications from a surface vessel, ROV to 6000 meter depth. 
Reson SeaBat 8101
The SeaBat 8101 Multibeam Echosounder measures discrete depths, enabling complex underwater features to be mapped with precision. Dense coverage is achieved utilizing up to 4,000 soundings per second for a swath up to 600 meters in width, even as the survey vessel travels at speeds in excess of 12 knots. 
Reson SeaBat 8124
Specially designed for harbor and river surveys, the SeaBat 8124 is ideal for condition and pay quantity surveys in support of dredging operations. 
Reson SeaBat 8125
The SeaBat 8125 is the first wide-sector, wide-band, focused multibeam sonar ever to be deployed. Utilizing 240 dynamically focused receive beams, the system measures a 120° swath across the seafloor, detects the bottom, and delivers the measured ranges at a depth resolution of 6 mm.
