4.3. Measuring range and bearing

It's worth reminding you at this point about the Range Bearing measuring tool ) which is frequently useful in analysis. The calculated range and bearing is displayed at the mid-point of the line and at the foot of the DebriefNG screen (where it remains until you make another measurement).

The default units for the range displayed are configured using the CMAP section of the Preferences dialog in the Window menu. The preferences page can also be accessed by double-clicking on the range/bearing slave display at the foot of the screen.

4.3.2. Earth Model

The Range Bearing calculation is performed using the algorithms in the current Earth Model, as described later in Section 18.1, “Range/Bearing calculations within Debrief”.
