Special Navigation Interfaces Using Delph Nav

72 CHAPTER 1: Using DelphNav™ (Survey Control Panel) 2004.06.28

To import the DDS_VIF file into DelphNav

1. Run DelphMap again, choose Project → Insert Layers, locate the DDS_VIF file of

interest, and open the DDS_VIF file to import it.

By default the color table applied to this file will be gray-scale, but a more advanta-

geous palette may be specified from

GIS Tools → Color Palettes. The resulting dia-

log box offers data type options for sidescan sonar, bathymetry, and other data types.

2. From

GIS Tools → Color Palettes select the Bathymetry data type and use the Jet

palette. Also see ‘Change the Color Palette Settings’ on page 28 of the Using

DelphMap technical manual for more information on color manipulation.

To compute a volumetric delta of channel ‘actual’ v. design

• For the procedure, see ‘Computing Volumetric Differences’ starting on page 114 of

the Using DelphMap technical manual.

Primary and secondary surfaces are selected from existing DDS_VIF files, with the output

being a user-defined volume layer. For example, the primary surface could be the channel

design raster layer and the secondary surface could be the processed multibeam data of the

seabed.

Accompanying this operation is an ASCII report having the suffix LOG, listing the volume

and surface area above and below the primary image.

Special Navigation Interfaces

DelphMap can work with a number of special navigation interfaces.
