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 theAttributeNames
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

Note: The member names in this class are upper-cases because they should be considered as constants. For exampleAttributeNames.LATITUDE.MINIMUM
maps exactly to the"geospatial_lat_min"
string and nothing else. A lower-caseminimum
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.- Since:

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"

and"time_coverage_start"
.

MAXIMUM

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"

public final String UNITS
The attribute name for the bounding box units of measurement. Possible values are"geospatial_lat_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, ornull
if none. By default,DimensionNameType.COLUMN
is associated to longitudes andDimensionNameType.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.
