Table 6.18 -- EDCS attributes whose label begins with N
| Label | Definition | Attribute value type | EQ label | Code |
| NAME | A textual identifier or code used to denote an <OBJECT>; the name. | STRING | 853 | |
| NATIONAL_PAINT_SCHEME | The national paint scheme applied to an <OBJECT>. The values are specified by a <<NATIONAL_PAINT_SCHEME_VALUE_SET>>. | CONSTRAINED_STRING | 854 | |
|
NATIONAL_PAINT_SCHEME_VALUE- _SET |
The value <SET> of a formatted <<NATIONAL_PAINT_SCHEME>>. | ENUMERATION | 855 | |
| NATIVE_SETTLEMENT_TYPE | The type of distribution of native <DWELLING>s. | ENUMERATION | 856 | |
| NAUTICAL_GATE_TYPE | The type of a <MARINE_GATE>. | ENUMERATION | 857 | |
| NAVIGATION_LIGHT_INTENSITY | A number between 0 and 1 inclusive representing the linearly-scaled fractional intensity of external <LIGHTING> used to illuminate the environment in the <DIRECTION> of travel of a <VEHICLE>; the navigation or head light intensity. Zero means minimum intensity and one means maximum intensity. | REAL | PURE_NUMBER | 858 |
| NAVIGATION_PATH_TYPE | The type of <LINE> defining a marine navigation path. | ENUMERATION | 859 | |
| NAVIGATION_SYSTEM_TYPE | The type of technology used in electronic navigation. The value is either a type of <EQUIPMENT> or the name of a <SYSTEM>. | ENUMERATION | 860 | |
| NOMINAL_LIGHT_RANGE | The maximum distance at which a <LIGHT> can be seen in clear weather as defined by the International Visibility Code; the nominal light range. | REAL | LENGTH | 861 |
| NON_SUB_CONTACT_DATE | The date of reporting of a non-submarine contact. A non-submarine contact is any <OBJECT> (for example: a <MARINE_WRECK>) on a <WATER_BODY_FLOOR> that could be mistakenly identified as an operable <SUBMERSIBLE_VESSEL> when detected with acoustic or magnetic sensors. | CONSTRAINED_STRING | 862 | |
|
NON_SUB_CONTACT_POSITION- _ACCURACY |
The accuracy of the <LOCATION> of a non-submarine contact. A non-submarine contact is any <OBJECT> (for example: a <MARINE_WRECK>) on a <WATER_BODY_FLOOR> that could be mistakenly identified as an operable <SUBMERSIBLE_VESSEL> when detected with acoustic or magnetic sensors. When the accuracy is uncertain, the value 10 000 kilometres is used. | REAL | LENGTH | 863 |
| NON_SUB_CONTACT_SOURCE | The source of a reported non-submarine contact. A non-submarine contact is any <OBJECT> (for example: a <MARINE_WRECK>) on a <WATER_BODY_FLOOR> that could be mistakenly identified as an operable <SUBMERSIBLE_VESSEL> when detected with acoustic or magnetic sensors. | ENUMERATION | 864 | |
| NON_SUB_CONTACT_SOURCE_TYPE | The source of a report of a non-submarine contact. A non-submarine contact is any <OBJECT> (for example: a <MARINE_WRECK>) on a <WATER_BODY_FLOOR> that could be mistakenly identified as an operable <SUBMERSIBLE_VESSEL> when detected with acoustic or magnetic sensors. | ENUMERATION | 865 | |
|
NON_SUB_CONTACT_WRECK- _IDENTIFIER |
The numeric identifier of a <MARINE_WRECK> or other non-submarine contact. A non-submarine contact is any <OBJECT> (for example: a <MARINE_WRECK>) on a <WATER_BODY_FLOOR> that could be mistakenly identified as an operable <SUBMERSIBLE_VESSEL> when detected with acoustic or magnetic sensors. | INDEX | 866 | |
| NULL | The null attribute concept; provided for information processing applications. | NULL | 867 | |
| NUMERIC_IDENTIFIER | A numeric identifier used to reference values in a data structure; an index. | INDEX | 868 | |
| NUMERIC_OBJECT_IDENTIFIER | The numeric identifier of an <OBJECT>. | INDEX | 869 |
