Examples of WKTWriter

pengis.org/techno/specs.htm"> OGC Simple Features Specification for SQL.
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 {@link LinearRing}s. Under the spec, rings are output as LINESTRINGs. In order to allow precisely specifying constructed geometries, JTS supports a non-standard LINEARRING tag which is used to output LinearRings. @version 1.7 @see WKTReader
