There's a lot of interpolation here, so having a wider swath of bathymetry that can give a hint of bottom roughness/smoothness would improve results. We also have projects with habitat mapping, where again we would look at depth, sidescan, and bottom classification from PSV, E1, E2. Customers are happy enough, but I am looking to improve my work and I think offering a better idea of the whole area than just a single-beam track is an easy way to go, where the Raymarine sonars appear to be shining brightest due to the IMU you put in the transducer. Then add sidescan to point out any big rocks etc in the vicinity. Currently for such a project I would just use the Lowrance single-beam to collect a few tracks, pull those tracks into ReefMaster, export depth as point and curves, and do a bottom classification on PSV, E1, and E2 and explain what they can expect. We take on a lot of low budget projects from customers who are not willing to do a full bathymetric survey, but want some idea of what is on the bottom of a river/lake/sea.įor example, we regularly have projects where a cable or pipe is put down on the bottom, or dug down, and the customer wants to know if there are big rocks that could cause problems or if the bottom is bedrock, and about how deep it is. Is there any software compatible with the RV transducers? If I connect an RV transducer to say a Raspberry Pi, how difficult would it be to figure out the communication protocol? Is it all binary, or is it serial? With serial it should be easy to get the data sorted, but I can't find any documentation about data transfers between the transducer and Axiom.Ĭheapest multibeam I could find costs around 30'000 €, so the RealVision 3D would be a great option if I could get it to work with transfer of data to PC. Hummingbird can get data into ReefMaster 2, but I am not sure if they have any other depth data than the single beam, so that the only wider data is the sidescan. From the Axiom screens I have seen, Raymarine RealVision has much better accuracy (perhaps due to the IMU included in the transducer?).
I have worked with the Lowrance StructureScan 3D data and it has rather poor accuracy so I would prefer to steer away from this option. SIMRAD and Lowrance (and presumably B&G) have TotalScan and StructureScan which can be read in both ReefMaster 2 and SonarWiz software, and probably other software too. RV transducers collect 3D bathymetry data, but for all my looking I can only find it being displayed in the Axiom MFD's.
I am on the hunt for a cheap alternative to multibeam to collect better depth data than singlebeam does.
