is dominant and subordinate layers cannot shine through. This is the

DelphMap default.

• Shinethrough – Min: The lowest value of all pixels falling within a grid

cell are used. Consequently, features in the imagery that were

ensonified from

weak or soft sonar returns have more opportunity to

“shine through” layers.

•

Shinethrough – Average: The average value of all pixels falling within a

grid cell are used. Consequently, no one layer dominates in the display,

and all prominent features in all layers have an equal chance to “shine

through” layers. However, even slight differences in navigation

occurring on adjacent lines can obscure features somewhat, so this

type of shine-through is not used very often.

•

Shinethrough – Max: The highest value of all pixels falling within a grid

cell are used. Consequently, features in the imagery that were

ensonified from

strong sonar returns have more opportunity to “shine

through” layers. This option is probably the most useful when you are

mosaicking data containing well-defined, prominent targets.

To change the shine-through overlap method

• From the main menu, access

GIS Tools→Display mode and choose a

shine-through method. There is no icon equivalent to access this

function.

Simulating ROV Flight or Dredging Routes

If you record your data as one or more XTF files and you have or had a Remotely

Operated Vehicle (ROV) or dredge equipment on the data survey, you can

simulate the route.

To use ROV Flight or Dredging simulation in playback mode

1. From DelphMap’s main menu, access one of these paths:

•

Applications→Rov Flight→Playback→Start

•

Applications→Dredging→Playback→Start

The system displays the Select input projection dialog box.

2. Choose an appropriate input projection for the data you are going to

play back and click Next.

3. Choose an appropriate input datum for the data you are going to play

back and click Finish.
