Saved files
When Saved files are selected, the StructureMap file is overlaid on the map based on position
information in the file.
If the chart scale is large, the StructureMap area is indicated with a boundary box until the
scale is large enough to show Structure details.
Saved mode is used to review and examine StructureMap files, and to position the vessel on
specific points of interest on a previous scanned area.
Ú
Note:
When saved files are used as the source, all StructureMap files found on the
memory card and in the system’s internal memory are displayed. If there is more than
one StructureMap of the same area, the images overlap and clutter the chart. If several
logs of the same area are required, the maps should be put on separate memory cards.
StructureMap tips
•
To get a picture of taller structures (a wreck, etc.) — do not drive over it, instead, steer the
boat so the structure is on the left or right side of your vessel.
•
Do not use Autorange when using StructureScan. Set your structure range to a
significantly greater level (two-to-three times) than the water depth to ensure a complete
scan and to maximize conversion accuracy.
•
Do not overlap history trails when conducting a side-by-side scan of an area.
Recording StructureScan data
StructureScan data can be recorded from a chart panel with Structure overlay enabled.
StructureScan recordings can also be started from a StructureScan panel.
When StructureScan data is being recorded, there is a flashing red symbol and a message
appears periodically at the bottom of the screen.
Ú
Note:
The message includes information about file size. Keep the size of your logs to
100MB or less to allow for faster file conversion.
The recording is stopped by re-selecting the record function.
Converting StructureScan data to StructureMap format
A StructureScan log file (.sl2) is converted to StructureMap format (.smf ) after recording from
the recording dialog, or from the files browser.
You can create standard or high resolution files. High resolution .smf files capture more detail,
but take longer to convert and are larger than standard resolution files.
To save disc space it is recommended to remove the StructureScan (.sl2) files after
conversion.
Using StructureMap with mapping cards
StructureMap allows you to maintain full chart capability and can be used with embedded
cartography as well as Navionics, Insight and other third-party charting cards compatible
with the system.
When using StructureMap with mapping cards, copy the StructureMap (.smf ) files to the
unit’s internal memory. We recommend keeping copies of StructureMap files on external
mapping cards.
Structure options
You adjust the StructureMap settings from the Structure options menu. The menu is
available when Structure overlay is enabled.
Not all options are available when saved StructureMap files are used as the source.
Unavailable options are greyed.
Range
Sets the search range.
