GEOS 3.3.0
Posted on by strk
Category: Free Software GIS
GEOS 3.3.0 is out: http://download.osgeo.org/geos/geos-3.3.0.tar.bz2
This release introduces a fair amount of new C-API interfaces and a brand new PHP binding. Full details in the NEWS file: http://trac.osgeo.org/geos/browser/tags/3.3.0/NEWS
As with any release since 3.0.0 there is complete binary compatibility with clients linked against the C-API. These include, but are not limited to, PostGIS. For a list of known clients: http://trac.osgeo.org/geos/wiki/Applications (add yours, if not already listed!)
GEOS is a C++ port of the JTS Topology Suite. This release targets version 1.12 of the library, but doesn’t reach full feature parity yet. Missing JTS functionalities:
- Densifier class
- Geometric similarity detection package (HausdorffSimilarityMeasure, AreaSimilarityMeasure)
- MinimumDiameter.getMiminumRectangle()
- Triangulation API
- VoronoiDiagramBuilder
- createSquircle and createSuperCircle in GeometricShapeFactory
- MinimumClearance class
- nearestNeighbours method to STRtree
- RandomPointsBuilder / RandomPointsInGridBuilder
- KochSnowflakeBuilder
- SierpinksiCarpetBuilder
If you’d like to sponsor development of any of the above items (or others) for next feature release of GEOS (3.4.0) please drop me a note.
