StructureMap™
HDS Gen 2 Addendum
StructureMap is a tool that allows you to overlay SideScan sonar returns on
top of the chart, giving you a birds-eye view of underwater structure below
and beside your boat.
StructureMap makes it easier for you to visualize the
underwater environment in relation to your position and aids the user in
interpreting sidescan sonar images.
Refer to your HDS manual for basic information about HDS unit operation.
Refer to your StructureScan manual for more information about
StructureScan.
Viewing StructureMap data
You can view StructureMap data by turning on Structure overlay from the
Chart menu, or by using the Overlay softkey (HDS-8/10). StructureMap data
will start to appear on the Chart screen as soon as Structure overlay is en-
abled. The Structure Source setting determines whether the StructureMap
information you want to view is live or previously recorded.
