Tides Tab
The
Tides
window allows you to change the way the WMB-X230 uses tide information. Assuming the
Disable Tides
check box is cleared, the WASSP system uses the GPS positioning information coming
through the WASSP Processor communications port to automatically select the closest tide station.
The WASSP system then calculates a tide offset value and adjusts the seafloor profile data using the
tide offset value.
Selecting the
Disable Tides
check box can cause the seafloor depth to vary as the tide waxes and
wanes, resulting in inconsistencies in seafloor mapping.
Disable Tides
should be selected if you are
working on a lake.
Enter the local time difference in hours (from Coordinated Universal Time UTC) into the
Local Time
difference
field to update the
Current Time
and
Next Tide
times to local time.
