In+ersec+ion for Spatial People

Good news, JTS 1.12 has been released. It matters since a lot of other open source software uses it. GEOS, which recently went to 3.3.0, is a C++ port of the JTS. We also mentioned a month ago the new JSTS project, the JavaScript port.

From it's main website, JTS is: "The JTS Topology Suite is an API for modelling and manipulating 2-dimensional linear geometry. It provides numerous geometric predicates and functions. JTS conforms to the Simple Features Specification for SQL published by the Open GIS Consortium."

What's new for 1.12:

• "Single-Sided Buffers
• MinimumClearance function
• nearestNeighbours methods for STRtree
• Vector2D class for vector operations
• DD (DoubleDouble) enhanced precision arithmetic
• improved robustness for Delaunay and Voronoi computation
• enhanced geometry digitization in the TestBuilder, along with a dynamic grid"
