Figure 37 shows SAMM’s GUI playing the sample data.
Live info, playback controls and processing controls appear in the Swath list’s place, and
the list has shifted to below the processing controls.

, referenced in the Swath list, is drawn behind the
vessel in the mosaic window.

The file playback progress is present in the status bar.
Figure 37. GUI in Playback Mode
This is the standard SAMM playback mode. You can pause, restart, slow down or accelerate
playback. During playback you can break swaths (use the Break swath button or B key), adjust
swath properties and update charts/views.
SAMM does not support adding data from widely disparate locations to the same project at this
time. Please start a new project for each new region of operation
.

Load Files from Directory
Similar to the Load files function, SAMM can load files from a selected directory. This mode
allows SAMM to monitor the selected directory and when new files are added to the directory,
SAMM automatically grabs them and adds to the mosaic. This mode is useful for sonar systems
to which SAMM currently does not interface in real-time but supports playback/load of the data
formats (e.g. Sound Metrics ARIS/DIDSON, Reson FLS, MST and XTF sidescan). During a
survey, as data acquisition software writes a new file to a folder that SAMM is monitoring, the
file gets loaded to SAMM and the mosaic updates. The update rate of the mosaic depends on
how often the data acquisition software writes data to a file. If a file creation interval is set small
(e.g. 10 seconds), SAMM can create mosaic in near-realtime.
