Status ▾	Attribute label	Enumerant label	Concept definition	Code	Ref type	Reference	Supplemental references
STD 2005/06/07	SOUNDING_DATUM_TYPE	HIGH_WATER_SPRINGS	An arbitrary level, approximating that of <<<MEAN_HIGH_SPRINGS>>>; mean high water springs.	11	PR	[S57A, Attribute, VERDAT:20]
STD 2005/06/07	SOUNDING_DATUM_TYPE	HIGHEST_ASTRONOMICAL- _TIDE	The highest <<TIDE_LEVEL>> that can be predicted to occur under average meteorological conditions and under any combination of astronomical conditions; highest astronomical tide.	12	PR	[S57A, Attribute, VERDAT:30]
STD 2005/06/07	SOUNDING_DATUM_TYPE	HIGHEST_HIGH_WATER	The highest water level observed at a <LOCATION>; highest high water.	13	IR	[FACC, Annex B, VDC:28]
STD 2005/06/07	SOUNDING_DATUM_TYPE	HIGHEST_NORMAL_HIGH- _WATER	Highest normal <<<HIGH_WATER>>>.	14	IR	[FACC, Annex B, VDC:26]
STD 2005/06/07	SOUNDING_DATUM_TYPE	IGLD_1985	A vertical reference system with its zero based on the mean water level at Rimouski/Pointe-au-Père, Québec, over the period 1970 to 1988; International Great Lakes Datum 1985.	15	PR	[S57A, Attribute, VERDAT:25]
STD 2005/06/07	SOUNDING_DATUM_TYPE	INDIAN_SPRING_HIGH_WATER	A <<TIDAL_DATUM>> approximating the level of the mean of the <<<HGHR_HIGH_WATER>>> at <SPRING_TIDE>s; Indian spring high water. This <<TIDAL_DATUM>> approximates the highest water level observed at a <LOCATION> and is usually above that of the <<<HGHR_HIGH_WATER>>> at <SPRING_TIDE>s.	16	IR	[FACC, Annex B, VDC:30]
STD 2005/06/07	SOUNDING_DATUM_TYPE	INDIAN_SPRING_LOW_WATER	A <<TIDAL_DATUM>> approximating the level of the mean of the <<<LOWER_LOW_WATER>>> at <SPRING_TIDE>s; Indian spring low water. This <<TIDAL_DATUM>>, which is also known as Indian tidal plane, approximates the lowest water level observed at a <LOCATION> and is usually below that of the <<<LOWER_LOW_WATER>>> at <SPRING_TIDE>s.	17	IR	[S57A, Attribute, VERDAT:8]	[FACC, Annex B, VDC:4]
STD 2005/06/07	SOUNDING_DATUM_TYPE	LOCAL_DATUM	An arbitrary <DATUM> defined by an authority of a local <HARBOUR>, from which levels and tidal heights are measured by this authority; local datum.	18	PR	[S57A, Attribute, VERDAT:24]
STD 2005/06/07	SOUNDING_DATUM_TYPE	LOW_WATER	An approximation of <<<MEAN_LOW_WATER>>> adopted as the reference level for a limited <REGION>, irrespective of better determinations later. Used mostly in <HARBOUR> and river engineering. Used in <INLAND_WATER>s. It is generally defined as a level which the daily mean water level would fall below less than 5 percent of the time and by no more than 0,2 metres during the navigation season. A single level <SURFACE> is usually chosen as the low water <DATUM> for a whole <LAKE>. On a <RIVER>, low water <DATUM> is a sloping <SURFACE>, which approximates the <WATERBODY_SURFACE> of the <RIVER> at a low state.	19	PR	[S57A, Attribute, VERDAT:13]	[TCG, "low water datum (LWD)", (2)]
STD 2005/06/07	SOUNDING_DATUM_TYPE	LOW_WATER_SPRINGS	A level approximating that of <<<MEAN_LOW_SPRINGS>>>; low water springs.	20	IR	[S57A, Attribute, VERDAT:9]	[FACC, Annex B, VDC:93]

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
