HyPAS creates a theme with vectors. These vectors are scaled using the total
velocity magnitude and displayed in the direction of flow (Figure 2-17).

Velocity Profiles
HyPAS will also allow the user to plot velocity profiles
of the ADCP data. Using ArcView, the desired point(s)
should be selected. Click the Plot Profile Curves button
(Figure 2-18) on the HyPAS menu to begin the process.
