Ah okay, thanks for the heads up. The sonar data is currently exported form my sonar device in excel / .csv format. Can the conversion to raster be done within a GIS program like SAGA or does that need to be done separately? – Liam Murphy Nov 5 '20 at 14:53

The sonar itself scans about 15 times per second, this is why most data lines are without coordinates. It is only possible to export bathymetric data created in Boat or On-shore GPS modes of the sonar. Recordings made Standard and Ice Fishing modes will contain only the sonar data, which cannot be exported.

Side-scan sonar mosaics are created and used together with detailed bathymetry to produce a map of the manmade and naturally occurring features on the seabed within the area surveyed. The results are output as raster geo-referenced tiffs of the side-scan sonar mosaics, contoured swathe bathymetry and an overlay of geophysical interpretation of ...

For bathymetric mapping of the subsurface geometry in lakes or the ocean, one common technology is sonar. See bathymetry for background information. The key concepts for the data manager to understand about terrain mapping using sonar include the following: The horizontal resolution and vertical accuracy of sonar systems is less than it is for ...

Before you can add your source datasets with the Add Bathymetry tool, define any required extended metadata fields for each file as well as some additional properties. Extended metadata fields can be updated for the datasets individually, across datasets in a particular folder location, or for all listed datasets.

ENC layers contain bathymetric measurements, land boundaries, and additional information about the seafloor and water currents in vector format making this data ideal for use in a GIS program. The vector features contained in these charts can be searched, filtered, and edited as any other vector data in Global Mapper.

How is sonar used to help map the ocean floor?

🗺️
From antiquity to World War I, the depth of the ocean was measured by using a weighted rope with markings on it. Once sonar became commercially available after World War I, sound was used to find the depth of the ocean. Low resolution satellite altimetry became available in the 1970s.

The satellites can measure very small diferences in sea-surface height. This data, like sonar, is also used to create detailed ocean floor maps. A submersible is a small underwater craft used for deep-sea research. Submersibles, unlike sonar or satellite, can take videos and pictures of animals that live at the deepest points.
The technique, first used by German scientists in the early 20th century, uses sound waves bounced off the ocean bottom.... In this way, they produced “bathymetry maps” that displayed the ocean's changing water depths (and hence changes in seafloor elevation).
High-resolution maps of the seafloor (bathymetric maps) are important for ship navigation, geological research, habitat and ecosystem studies, and military activities. From antiquity to World War I, the depth of the ocean was measured by using a weighted rope with markings on it. Once sonar became commercially available after World War I, sound was used
Seismic reflection and seismic refraction, used to study the layers below the sea floor, also produce an ocean sea floor map. While faster and more accurate than traditional methods, echosounding only measures a single location directly under the ship and is inefficient for mapping large areas of the ocean floor.
SONAR, short for SOund NAvigation and Ranging, is a tool that uses sound waves to explore the ocean. Scientists primarily use sonar to develop nautical charts, locate underwater hazards to navigation, search for and identify objects in the water column and on the seafloor such as shipwrecks, and map the seafloor itself.

Surveys with BAGs: A Bathymetric Attributed Grid (BAG) is a non-proprietary file format for storing and exchanging bathymetric data developed by the Open Navigation Surface Working Group. BAG files are gridded, multi-dimensional bathymetric data files and are the standard NOS hydrographic data file for public release.
Lowrance GPS Sonar devices are not made in China. From what I could find online, it appears these devices are actually manufactured and shipped from Indonesia.
Multiple methods can be used for bathymetric surveys including multi-beam and single beam echo sounder surveys , Acoustic Doppler Current Profiler (ADCPs), sub-bottom profilers, and the Eco-mapper Autonomous Underwater Vehicle, which was advanced by light detection and ranging (LIDAR) datasets.
With these systems onboard, a submarine can be accurately navigated and be within a hundred feet of its intended course. To locate a target, a submarine uses active and passive SONAR (sound navigation and ranging). Active sonar emits pulses of sound waves that travel through the water, reflect off the target and return to the ship. By knowing the speed of sound in water and the time for the sound wave to travel to the target and back, the computers can quickly calculate distance between the...
