7.1 Swath Editor
The Swath Editor in Perspective allows the user to edit the beam flags in the GSF file
associated with the selected navigation line. Beam flags are used in the processing wizard
to decide if the sounding will contribute to the grid cell value or not, and if so how it
contributes. The
Swath Editor can assign three different beam flags to a sounding:
 Good: use this sounding in the gridding process according to the specified
encoding method.
 Bad: ignore this sounding in the gridding process
 Designated: use to set a sounding as the value to use for the grid cell. If more
than one designated sounding exists in a single grid cell than the specified encoding
method will be used but only on the designated soundings.
To launch the Swath Editor , there are two methods depending on your purpose:
1. To review areas with noise or high standard deviation/uncertainty values, double-
click on the bathymetry navigation line in the map view at the location of interest.
2. To review the entire data line from start to end, right-click on the navigation line in
the file tree and select Edit Swath . This will open the Swath Editor at the
beginning of the line.
When the Swath Editor launches,
four panels will appear, three data
views, plus the
Control Panel shown
to the right.
Note the Ping Index can be used to
locate a particular ping, and the
slider bar at the bottom allows the
user to move quickly to another
location in the data file.
Setting the Sweep Length adjusts
the number of pings viewed in the
data view windows. For reviewing
