Aspose.GIS for .NET 18.9 Release Notes

Major Features

Major features and improvements in this release:

  • Determining the spatial relation between geometries (e.g. testing if geometries intersect, testing if one geometry contains another, etc.).
  • Computing Intersection, Union, Difference and Symmetric Difference between geometries.
