public enum Convention extends Enum<Convention>
AXIS[…]elements in the WKT.
WKT1_COMMON_UNITSenumeration allows parsing and formatting using the older interpretation. The
WKT1_IGNORE_AXESenumeration mimics the most minimalist WKT 1 parsers, but should be avoided when not imposed by compatibility reasons.
|Enum Constant and Description|
A special convention for formatting objects as stored internally by Apache SIS.
The OGC 01-009 format, also known as “WKT 1”.
The Simple Feature format, also known as “WKT 1”.
The Simple Feature format without parsing of axis elements.
The ISO 19162 format, also known as “WKT 2”.
The ISO 19162 format with omission of some optional elements.
|Modifier and Type||Method and Description|
Returns the major version of the Well Known Text represented by this convention.
Returns the enum constant of this type with the specified name.
Returns an array containing the constants of this enum type, in the order they are declared.

GeocentricCRS, WKT 1 uses a legacy set of Cartesian axes which were defined in OGC 01-009. Those axes use the Other, Easting and Northing axis directions instead than the geocentric ones. For more uniform handling of CRS objects in client code, SIS parser replaces some WKT 1 conventions by the ISO ones when possible.

This convention is identical to
WKT1 except for the following aspects:
PARAMETERelements are always degrees, no matter the units of the enclosing

WKT1_COMMON_UNITSexcept that all
AXIS[…]elements are ignored. Since the WKT 1 specification said that the default axis order shall be (x,y) or (longitude, latitude), ignoring
AXIS[…]elements is equivalent to forcing the coordinate systems to that default order.
AXIS[…] elements still need to be well formed even when parsing a text with this convention.
Malformed axis elements will continue to cause a
ParseException despite their content being ignored.
This convention may be useful for compatibility with some other softwares that do not handle axis order correctly. But except when imposed by such compatibility reasons, this convention should be avoided as much as possible.

Parameterelements omit the unit of measurement if that unit is equal to the default unit (as declared in the parameter descriptor).
CompoundCRSelements show nested compound CRS if any (the structure is not flattened).
Idelements are formatted for child elements in addition to the root one.
