java.lang.Objectcom.vividsolutions.jts.io.WKTWriter
public class WKTWriter
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 LinearRing
s.
Under the spec, rings are output as LINESTRING
s.
In order to allow precisely specifying constructed geometries,
JTS also supports a non-standard LINEARRING
tag which is used
to output LinearRings.
