Refractions Research has joined the Google "Summer of Code" as a mentoring organization. That means we are hoping to get some great proposals from students looking to enhance PostGIS as a "Summer of Code" project.

If you are a student, check out the ideas page for what we have already brain-stormed as potential projects. If you just have an idea for a Summer of Code project, raise it on the postgis-users mailing list.

We are looking for good projects that will help move the project forward, but can be realistically completed within the course of a summer.

  • Changed Z() function to return NULL if requested dimension is not available
• Peformance improvements:
  • Much faster transform() function, caching proj4 objects
  • Removed automatic call to fix_geometry_columns() in AddGeometryColumns() and update_geometry_stats()
• JDBC2 upgrades:
  • Makefile improvements

Refractions Research has led a project to fund the improvement of locking and concurrency in the PostgreSQL GiST index subsystem. The improvements will dramatically improve read/write performance of PostGIS starting with the PostgreSQL 8.1 release. developers.

The 1.0.4 release includes a number of small bug fixes and one large bug fix for memory management when building spatial indexes. Users with very large databases may have experienced out of memory errors prior to this fix.

The 1.0.3 release includes a number of small bug fixes and one large bug fix for bounding box calculation. This bug will affect indexing in rare cases.
