Examples of com.vividsolutions.jts.geom.GeometryFactory

com.vividsolutions.jts.geom.GeometryFactory
Supplies a set of utility methods for building Geometry objects from lists of Coordinates.
Note that the factory constructor methods do not change the input coordinates in any way. In particular, they are not rounded to the supplied PrecisionModel. It is assumed that input Coordinates meet the given precision. @version 1.7
