Hi all users of GEOS, GEOS 3.8.0 has been released!
http://download.osgeo.org/geos/geos-3.8.0.tar.bz2 This is a performance and internals release, primarily, that has ported many improvements in from JTS, added arbitrary precision support to improve operation robustness, modernized the use of C++ idiom in much of the code base, and applied numerous performance improvements, both algorithmic from JTS and in the C++ implementation practices. Thank you to everyone who has contributed! Please report any issues you find in building or running tests on the GEOS ticket tracker https://trac.osgeo.org/geos/ or to this list. - New things: - CAPI: GEOSBuildArea (#952, Even Rouault) - CAPI: GEOSMakeValid (#952, Even Rouault) - CAPI: GEOSPolygonize_valid (#727, Dan Baston) - CAPI: GEOSCoverageUnion (Dan Baston) - CAPI: GEOSCoordSeq_setXY, GEOSCoordSeq_setXYZ, GEOSCoordSeq_getXY, GEOSCoordSeq_getXYZ (Dan Baston) - CAPI: GEOSMinimumBoundingCircle (#735) - CAPI: GEOSGeom_createPointFromXY (Dan Baston) - Improvements: - Improve overall performance by reducing of heap allocations (Dan Baston) - Improve performance and robustness of GEOSPointOnSurface (Martin Davis) - Improve performance of GEOSPolygonize for cases with many potential holes (#748, Dan Baston) - Support extended precision calculations (ttmath) and port JTS improvements related to extended precision (Paul Ramsey, Mateusz Loskot) - Improve performance of GEOSPolygonize for cases with many or complex shells (Dan Baston, Martin Davis) - Improve performance of Delaunay triangulations / Voronoi Diagrams (Dan Baston) - Improve performance of prepared geometry operations (Dan Baston) - Improve robustness of Delaunay triangulations (Paul Ramsey, Martin Davis) - Improve performance of unary union for lines (Dan Baston) - Improve general predicate, overlay, and buffer performance (Dan Baston, Paul Ramsey) - Improve cascaded union performance (Paul Ramsey, Martin Davis) - Allocate default GeometryFactory singleton on the stack (Sandro Mani) - Harmonize XML tests with JTS and harmonize cmake/autoconf test running (Paul Ramsey) - CMake modernization (Mateusz Loskot, Paul Ramsey, Dan Baston) - Return unique_ptr from most methods that produce a new geometry (Dan Baston) - Changes: - Constructive geometry functions in CAPI now preserve SRID of input arguments in output (#896) _______________________________________________ geos-devel mailing list email@example.com https://lists.osgeo.org/mailman/listinfo/geos-devel
