Author: Paul Ramsey  2015/10/07  in news ( release, 2.2, 2.2.0 )

PostGIS 2.2.0 is released! Over the last two years a number of interesting new features have been added, such as:

  • True nearest-neighbor searching for all geometry and geography types
  • New volumetric geometry support, including ST_3DDifference, ST_3DUnion and more
  • Temporal data model support and functions like ST_ClosestPointOfApproach to support temporal query
  • Spatial clustering functions ST_ClusterIntersecting and ST_ClusterWithin
  • Subdividing large geometries with ST_Subdivide
  • Fast box clipping with ST_ClipByBox2D
  • In-database raster processing with ST_Retile and ST_CreateOverview.html
  • New high-speed native code address standardizer
  • Visvalingam-Whyatt geometry simplification with ST_SimplifyVW
  • Support for compressed “tiny well-known binary” format with ST_AsTWKB and ST_GeomFromTWKB

See the full list of changes in the news file and please report bugs that you find in the release.

PostGIS 3.1.0

The PostGIS Team is pleased to release the release of PostGIS 3.1.0!

This version exposes the new features of GEOS 3.9 as well as numerous core performance enhancements for spatial joins, large object access, text format output and more.

Performance is a key feature of this release, with improvements to spatial joins, text outputs, large object reads, vector tile output, and a host of smaller tweaks.

The k-means clustering code has been enhanced to support weighting and higher dimensional clusters.

Geometry generators to create hexagonal and square tilings have been added, for simpler in-the-database summarization queries.

Finally, PostGIS exposes the latest enhancements in the GEOS geometry library 3.9 version. The new overlay engine (aka “OverlayNG”) provides more robust handling of difficult input geometries, using a set of new noding strategies to process geometry. For the end user, this should mean no more “topology exceptions” when using the union, difference, intersection or symmetric difference functions. PostGIS also exposes the new fixed precision overlay capability via an additional grid-size parameter on ST_Intersection and the other overlay functions.
