Code: VERACC

Type: real

Units: Metre

Attribute: Vertical clearance

Definition: The vertical clearance measured from the plane towards the object overhead.

Remarks: In the case of cables carrying high voltages an additional clearance of from 2 to 5 metres may be needed to avoid an electrical discharge. When known, the authorized safe clearance (known in the UK as the Safe Overhead Clearance) which is the physical clearance minus a safety margin shall be stated (IHO Chart Specifications, M-4). See also 'vertical clearance safe'. The unit of measure is defined in the HUNI subfield of the DSPM record or in the HUNITS attribute of the M_UNIT meta object class, e.g., metre (m). The resolution is 0.1 m or 0.1 ft.

Code: VERCLR

Type: real

Units: Metre

Attribute: Vertical clearance, closed

Definition: The vertical clearance of an object in closed condition (e.g., a closed lifting bridge) measured from the plane towards the object overhead.

Remarks: The unit of measure is defined in the HUNI subfield of the DSPM record or in the HUNITS attribute of the M_UNIT meta object class, e.g., metre (m). The resolution is 0.1 m or 0.1 ft.

Code: VERCCL

Type: real

Units: Metre

Code: VERCOP

Type: real

Units: Metre

Attribute: Vertical clearance, safe

Definition: The safe vertical clearance measured from the plane towards the object overhead.

Remarks: In the case of cables carrying high voltages, the quoted vertical clearance (VERCLR) may have to be reduced by 2 to 5 metres to avoid electrical discharge. When known, this authorized safe clearance (known in the UK as the Safe Overhead Clearance) which is the physical clearance minus a safety margin shall, be stated (IHO Chart Specifications, M-4). See also 'Vertical Clearance'. The unit of measure is defined in the HUNI subfield of the DSPM record or in the HUNITS attribute of the M_UNIT meta object class, e.g., metre (m). The resolution is 0.1 m or 0.1 ft.

Code: VERCSA

Type: real

Units: Metre

Attribute: Vertical datum

Definition: The datum to which both heights (vertical datum, see S-57 Part 3) and soundings (sounding datum, see S-57 Part 3) are referred.

Remarks: When the vertical datum is unknown, such as water areas above locks, the value "local datum" is to be used, and further details may be encoded using "INFORM". The +0.3m approximation quoted in the "approximate" levels is somehow arbitrary and follows the British example of their definition for "approximate LAT".
