• v1.16.0 Changes

  September 19, 2018

  🚀 The JTS team is pleased to share the JTS 1.16.0 release.

  🚀 If anyone finds issues with this release, please post them to our mailing list or as issues on the JTS GitHub site.

  API Changes

  • ➕ Added XYZM support to CoordinateSequence and CoordinateSequenceFactory with getDimension() and getMeasures() information.
  • Introduced Coordinate methods for getX(), getY(), getZ(), and getM().
  • 🗄 Deprecated Coordinate.z field, use Coordinate.getZ()
  • Coordinate subclasses introduced for XY, XYM, XYZM representations.

  Functionality Improvements

  • ✂ Removed PackedCoordinateSequenceFactory constructor used to supply a default dimension, use appropriate create( size, dimension ) instead.
  • 👍 WKTReader and WKTWriter support for measures

  Acknowledgments
