Waypoints and markers can be defined two different ways.
1. Waypoints, and general purpose markers can be entered into properly format-
ted text file and imported into Sonar View's coverage map.
2. Using an interactive tool window, waypoints, and general purpose markers
can be added during operation.
Entering waypoints and general purpose marker location into a text file
·
Use a text editor such as Notepad.
·
The text file must be stored as an ASCII text file with the ".txt" extension
·
The file text must be formatted as such:
o Latitude and longitude are formatted degrees, decimal minutes
(DD : MM.MMMM)
o The sentence structure is:
Latitude, Longitude, Show Marker/Waypoint (Y or N), ID Text
o Colons (:) must be used to separate degrees and Minutes.
o Commas (,) must be used to separate each fields.\
o The list of waypoints must have the header "Waypoints:"
(The headers are what the software used to determine what kind of
marker to place)
o The list of general purpose markers must have the header "Markers:"
(The headers are what the software used to determine what kind of
marker to place)
*Note: A sample text file can be found in the
"JW Fishers\Sonar View\Sample Data Files" folder.
