Figure 18. The 3D Sonar Display
In standard mode (see figure 19), the data is shown with perspective turned off (orthographic projection)
with the user looking down on the data. This looks much like a common radar display. However, where radar
gives a picture of what is above the water, FarSounder’s sonar displays a picture of what is below the water.
As with the 3D volumetric mode, the standard mode has color mapped to depth and zoom capabilities.
Figure 19. Standard Mode
In both modes, a white line (or plane) is shown. This is the Profile Selector. The Profile Selector denotes
the angle along which a 2D depth profile ahead of the vessel is shown in the Profile View. The number at
the end of the profile selector denotes the bearing of the profile selector relative to the vessel's bow or the
actual compass heading. This option is configured in the 3D sonar view's configuration options. The depth
profile slice specified with the Profile Selector is shown in the Profile View.
5.3. Profile View
The Profile View shows the depth profile (bathymetry) ahead of the vessel at the bearing selected by the
Profile Selector in either the 3D Volumetric or Standard View. The bearing angle of the Profile Selector and
the depth profile currently selected is shown in the lower left corner of the Profile View. In the Configuration
Manager options, the user can select between displaying the Profile Selector bearing relative to either the
vessel or the absolute heading.
