Class AttributeNames.Dimension

  • All Implemented Interfaces:

    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.
