## Class AttributeNames.Dimension

- Object
- - AttributeNames.Dimension

- All Implemented Interfaces:
    Serializable
  Enclosing class:
    AttributeNames

      public static class AttributeNames.Dimension
      extends Object
      implements Serializable

  Holds the attribute names describing a simple latitude, longitude, and vertical bounding box. In the following table, the header lists the constants defined in the `AttributeNames` class and the other cells give the values assigned in this class fields for those constants.

  Names of netCDF attributes describing an extent
  Field in this class | `LATITUDE` | `LONGITUDE` | `VERTICAL` | `TIME`
  --- | --- | --- | --- | ---
  `MINIMUM` | `"geospatial_lat_min"` | `"geospatial_lon_min"` | `"geospatial_vertical_min"` | `"time_coverage_start"`
  `MAXIMUM` | `"geospatial_lat_max"` | `"geospatial_lon_max"` | `"geospatial_vertical_max"` | `"time_coverage_end"`
  `SPAN` |  |  |  | `"time_coverage_duration"`
  `RESOLUTION` | `"geospatial_lat_resolution"` | `"geospatial_lon_resolution"` | `"geospatial_vertical_resolution"` | `"time_coverage_resolution"`
  `UNITS` | `"geospatial_lat_units"` | `"geospatial_lon_units"` | `"geospatial_vertical_units"` | `"time_coverage_units"`
  `POSITIVE` |  |  | `"geospatial_vertical_positive"` |
  `DEFAULT_NAME_TYPE` | `DimensionNameType.ROW` | `DimensionNameType.COLUMN` | `DimensionNameType.VERTICAL` | `DimensionNameType.TIME`

  Note: The member names in this class are upper-cases because they should be considered as constants. For example `AttributeNames​.LATITUDE​.MINIMUM` maps exactly to the `"geospatial_lat_min"` string and nothing else. A lower-case `minimum` member name could be misleading since it would suggest that the field contains the actual latitude value rather than the key by which the value is identified in a netCDF file.

- - ### Field Detail

    - #### MINIMUM

          public final String MINIMUM

      The attribute name for the minimal value of the bounding box (Recommended). Possible values are `"geospatial_lat_min"`, `"geospatial_lon_min"`, `"geospatial_vertical_min"` and `"time_coverage_start"`.

    - #### MAXIMUM

          public final String MAXIMUM

      The attribute name for the maximal value of the bounding box (Recommended). Possible values are `"geospatial_lat_max"`, `"geospatial_lon_max"`, `"geospatial_vertical_max"` and `"time_coverage_end"`.

    - #### SPAN

          public final String SPAN

      The attribute name for the difference between the minimal and maximal values. Possible value is `"time_coverage_duration"`.

    - #### RESOLUTION

          public final String RESOLUTION

      The attribute name for a further refinement of the geospatial bounding box (Suggested). Possible values are `"geospatial_lat_resolution"`, `"geospatial_lon_resolution"`, `"geospatial_vertical_resolution"` and `"time_coverage_resolution"`.

    - #### UNITS

          public final String UNITS

      The attribute name for the bounding box units of measurement. Possible values are `"geospatial_lat_units"`, `"geospatial_lon_units"`, `"geospatial_vertical_units"` and `"time_coverage_units"`.

    - #### POSITIVE

          public final String POSITIVE

      The attribute name for indicating which direction is positive (Suggested). Possible value is `"geospatial_vertical_positive"`.

    - #### DEFAULT_NAME_TYPE

          public final DimensionNameType DEFAULT_NAME_TYPE

      The default ISO-19115 dimension name type, or `null` if none. By default, `DimensionNameType​.COLUMN` is associated to longitudes and `DimensionNameType​.ROW` to latitudes since geographic maps in netCDF files are typically shown horizontally.

      The default associations may not be always correct since the columns and rows can be anything. Strictly speaking, the dimension name types shall be associated to the grid axes rather than the coordinate system axes. However the default association is correct in the common case (for netCDF files) where there is no axis swapping in the grid to CRS conversion.

    - #### Dimension

          public Dimension(DimensionNameType type,
                           String min,
