STD
2005/06/07
SOUNDING_DATUM_TYPE APPROX_MEAN_SEA_LEVEL An approximate level, usually within 0,3 metres from that of <<<MEAN_SEA_LEVEL>>>. 5 IR [S57A, Attribute, VERDAT:19] [FACC, Annex B, VDC:98]

SOUNDING_DATUM_TYPE CHART_DATUM_UNSPECIFIED Chart <SURFACE_DATUM> is unspecified. 6 IR [FACC, Annex B, VDC:21]  
STD
2005/06/07
SOUNDING_DATUM_TYPE EQUINOCTIAL_SPRING_LOW-
_WATER
The level of <<<LOW_WATER_SPRINGS>>> near the time of an equinox; equinoctial spring low water. 7 PR [S57A, Attribute, VERDAT:22]  
STD
2005/06/07
SOUNDING_DATUM_TYPE HGHR_HIGH_LARGE_TIDE The mean of the <<<HIGHEST_HIGH_WATER>>>s, one from each of 19 years of observations; higher high water large tide. 8 PR [S57A, Attribute, VERDAT:28]  
STD
2005/06/07
SOUNDING_DATUM_TYPE HGHR_HIGH_WATER The highest of the <<<HIGH_WATER>>>s (or single <<<HIGH_WATER>>>) of any specified tidal day due to the declinational effects of the <MOON> and <SUN>; higher high water [TCG, "higher high water (HHW)"]. 9 IR [FACC, Annex B, VDC:3]  
STD
2005/06/07
SOUNDING_DATUM_TYPE HIGH_WATER The highest level reached at a <LOCATION> by the <WATERBODY_SURFACE> in one tidal cycle; high water. When used on <INLAND_WATER>s, high water is generally defined as a level that the daily mean water level exceeds less than 5 percent of the time. 10 PR [S57A, Attribute, VERDAT:18]  

Group membership:

In addition to the status and date information for each entry, a colour coding scheme highlights the database holding to which an entry belongs. The following highlight colours are used:

  • white - the entry is in the standard
  • yellow - the entry has been added to the register
  • pink - the entry has been submitted for inclusion in the register, but it is not approved
  • cyan - a deprecated entry that was originally either in the standard or was added to the register, but has since been deprecated

The following icons are used to identify items that have figures, modifications and/or clarification notes:

  • F n - has Figures and, if more than one figure, n figures
  • M - has Modifications
  • C - has Clarifications
