StructureMap
The StructureMap feature overlays SideScan images from a
StructureScan source on the map. This makes it easier to visualize
the underwater environment in relation to your position, and aids in
interpreting SideScan images.
The StructureMap image
The example below shows a chart panel with Structure overlay,
combined with a traditional SideScan panel.
You move around in the chart as usual when you have a Structure
overlay:
• Touch operation: zoom the chart and the scanned image by
using the zoom (+ or -) buttons, or by pinching or spreading on
the screen. Drag on the panel to view the scanned image.
• Key operation: zoom the chart and the scanned image by using
the

option removes the cursor from the
panel, and the chart center is positioned at the vessel.
