If it is possible to implement this in RM v3, create CSV files from the sonar logs, which are included in the project with depth corrections. In version 2, there is partly such an opportunity, but you need to manually select from which logs to create a CSV. I, and I think many also, have added logs, but not all are included in the project and it can be difficult to sort them out a lot. It would be very useful for further work in GIS programs.
