Single beam processing

In Hydromagic Survey version 6.0 and higher, recorded data is saved as 'raw data files.' To create filtered, corrected and synchronized sounding data that can be used to calculate volumes, depth contours, digital terrain models and more, we need to process the previously recorded raw data files.

The sounding wizard

The sounding wizard is one of the most important tools in the Hydromagic Survey software. It allows you to convert one or more raw data files into corrected sounding files.

The sounding wizard leaves the original recorded data intact (in the "RawData" project folder) and creates a second set of data files to track all the changes you made (in the "Modified" project folder).

This method allows you to do corrections and filtering over and over again until you are fully satisfied with the result. If the data becomes corrupted, just instruct the wizard to start over with the original raw data files.

Starting the sounding wizard

When you finished recording one or more raw data files, you can combine data from these files into sounding files. To do so, you have to select the "Generate Soundings..." option from the "Tools" menu. Alternatively, you can start this wizard by right clicking the "Raw Data" folder in the project tree and selecting the "Process Raw Data File(s)..." option from the pop-up menu that appears as shown below:

Select the "Process Raw Data File(s)..." option from the pop-up menu.

The introduction page of the sounding wizard

You are now ready to create sounding files by performing a couple of steps which will be discussed in the next chapters. The first page of the wizard tells you what to expect in the next few steps. After quickly reading this information, click "Next" to proceed to the raw data selection step.

The first page of the wizard shows some information on the steps to follow.
