Format01 message format
The Format01 message, formerly called the SESAM format, used by the Dutch Ministry
of Infrastructure and the Environment (Rijkswaterstaat), is only defined for the heave and
the 10 second mean (H parameter). It consists of 8 character lines (Line-Feed character +
status character + sign character + 4 character value in cm + Carriage-Return character).
For a regular message the status character is a space. If an error occurs the status character
becomes a letter A. An example of the output strings in the RWS format is,
+0001
- 0004
A+9999
Format02 message format
Modifications can be made up on request. For example, the Korean Meteorological Admin-
istration (KMA) preferred a readable time format in the Korean time zone. An example of
the output strings in the KMA format is:
time=2018/01/25 21:55:00;H1=-266.33362cm;
time=2018/01/25 21:44:00;Hm0=1.2197564cm;
time=2018/01/25 21:56:00;H1=-266.41037cm;
Format03 message format
The Format03 message, formerly called the FGTI format, is used by the Belgium govern-
ment. Where one string is used for all required information (parameters + spectrum) per
processing interval. The chosen parameters are separated by a semicolon (;) and the 51
spectrum values (czz10) are included. The ’NaN’ string is replaced with a ’-9999’ string.
An example of the output string in the FGTI format is:
time=1516884540000;sensor=wob;Hm0=1.2876906cm;H1/3=1.2812848cm;Czz10=0.0,0.008055651,
