Detailed Description

Writes the Well-Known Text representation of a Geometry.

The Well-Known Text format is defined in the OGC Simple Features Specification for SQL. See WKTReader for a formal specification of the format syntax.

The WKTWriter outputs coordinates rounded to the precision model. Only the maximum number of decimal places necessary to represent the ordinates to the required precision will be output.

The SFS WKT spec does not define a special tag for LinearRings. Under the spec, rings are output as LINESTRINGs. In order to allow precisely specifying constructed geometries, JTS also supports a non-standard LINEARRING tag which is used to output LinearRings.

Version: 1.7

◆ write() [2/2]

void write	(	Geometry	geometry,
		Writer	writer
	)		throws IOException

Converts a Geometry to its Well-known Text representation.

Parameters

geometry a Geometry to process

◆ writeFormatted() [1/3]

String writeFormatted ( Geometry geometry )

Same as write, but with newlines and spaces to make the well-known text more readable.
