JTS Geometry operations are used to perform a range of spatial calculations; from finding an intersection to determining the centriod.

  • Intersection
  • ConvexHull
  • Intersection
  • Union
  • Difference
  • SymDifference

The JTS Geometry operations closely follow the simple features for sql specification; so if you have any questions on exactly what is going on please review the related specification.
