Add Files or Begin Acquisition 

SAMM can mosaic data in acquisition, playback, or post-processing modes. To mosaic data 
properly, SAMM accesses two classes of data: the sonar data itself and metadata. When in 
playback or post-processing mode, SAMM gets these data from the raw data files. During 
acquisition, however, SAMM receives these data either as they are broadcast from the sonar 
software, or directly from the sensors. 

At this time, Marine Electronics, R2Sonic, Tritech Gemini 

and Imagenex 881L-GS/882L owners must interface directly with the navigation/heading 
sources and the sonar, and other sonar systems interface to the position and heading feeds 
with the native sonar software. 

 
The first part of this section describes how to start a project in post-processing or playback 
mode by adding data files to the project. The second part describes how to load data from 
directory, which can be used to build a near-realtime mosaic during data acquisition. The third 
part describes how to interface with the metadata sources, and the Fourth part provides 
instructions for interfacing with supported sonar systems. The Add data dropdown menu (Figure 
34), accessed by clicking the 

Add data

 icon, controls file loading and interfacing with a sensor 

or sonar software program.

Add Files in Playback or Post-Processing Mode 

Supported data formats for post-processing and playback include M3 processed data files 
(*.imb), BlueView (*.son), ARIS/DIDSON (*.aris/*.ddf), Tritech Starfish (*.logdoc), EdgeTech 
(*.jsf), Klein (*.sdf), Reson/Norbit (*.s7k) and OIC SAMM (*.msk) and GeoDAS (*.oic). We 
suggest you practice with SAMM in playback mode prior to conducting a survey in acquisition 
mode. 
 

6.1.1  Load Files 

Load files option allows the user to select a collection of data files of the same type to generate 
mosaic without viewing the data. The resulting mosaic can be composed of numerous swaths, 
each of which is created from raw data files that are continuous in time. Therefore, if the data 
files were continuously recorded throughout the survey, the mosaic will have only one swath. If 
the data logging was paused during turns, the mosaic will have the number of swaths equal to 
the number of survey lines.
