6.6. Local History Mapping™

The Local History Mapping™ feature in SonaSoft™ persists seafloor data received over the last hour of
operation in the chart display. To generate the display, realtime data is 'gridded' into a regular Cartesian
grid with 4 meter grid spacing. Data in the LHM display is corrected for tide height for customers with a valid
C-MAP Profe license. The tide correction is a prediction based on historical data from the nearest
tide station in the C-MAP Profe database to the vessels current position. Figure 47, “Local History
Mapping  Overlay™”  depicts  the  LHM  overlay  on  the  chart  viewer.  Color  is  mapped  to  depth,  where  the
blue and yellow ends of the scale represent a seafloor depth of 20 meters and 2 meters, respectively. The
contours representing the channel are clearly visible in Figure 47, “Local History Mapping Overlay™” and in
agreement with the underlying nautical chart. The vessel track history (see the section called “Track History
Length”) is also visible and shows the vessel's position throughout the duration of the survey.

6.7. Requirements

In order to take advantage of the chart dispaly in SonaSoft™, the following must be configured on each
computer where the Chart Display will be used.

• C-MAP chart database must be installed. Currently supported databases are:

• Profe database from C-MAP
