A bay closing line is a set of one or more lines that spans the opening of a bay. For Law of the Sea, a bay closing line is legal if it meets these criteria:
• The combined length of all lines is less than or equal to 24 nautical miles.
• The area of the bay is greater than or equal to the area of a semi-circle with a diameter that equals the combined length of all lines required to close the bay.
This command checks the legality of an existing bay area and generates two kinds of reports.
If you send the report to the output window, it contains the following information:
• The area of the bay
• The area of the semi-circle created from the bay closing line
• The length of the bay closing line
• The status of the length and area criteria (PASS or FAIL)
• The legality of the bay closing line (YES or NO)
• The start point, end point, length and azimuth of each segment of the bay closing line.
If you save the report as a file, the information is saved in three separate files:
• area: Comma-separated file named <name>_areas.csv.
• baseline: Comma-separated file named <name>_baselines.csv.
• datum: Text file named <name>_datum.txt. The <name> value is defined in the Name field.
These files are saved in ...\CARIS\HPD\4.0\Tools\Reports\ Bay_Closing.
