Version 0.6.2 is mostly a bug fix release with fixes for
the Shape file loader. There is also a SQL file full of spatial reference
definitions to load into the SPATIAL_REF_SYS table.
Astute observers will note the addition of the postgis_chip.c
file. This is the start of support for raster datatypes. There is no
documentation on this because it is still in development and completely
unstable.
The basic idea is that large rasters can be subdivided into
smaller chips for storage. The chips will be small enough to fit within
the PostgreSQL page size (about 8kb). The chips will be indexable
(eventually) and there will be client functions available to retrieve
sets of chips and aggregate them into a single image. The result will be
random access raster coverages.
The slideshow Dave used for his
OSDB2 presentation is
available (PDF|PPT|Japanese PPT).
Without his inimitable delivery, it is not nearly the same. :)
We have a new, hopefully more aesthetically pleasing, site design now! At
a minimum, the multiple-page approach gives more space for adding information.
Also, version 0.6.1 has been released,
with improvements to the loader/dumper and some cygwin bug fixes.
Yet more OGC specification functions,
changes to internal format to support SRID, added SPATIAL_REF_SYS and
GEOMETRY_COLUMNS metadata tables. Upgraded Mapserver support.
Dave Blasby will be giving a presentation on spatial databases in
general and PostGIS in particular at the Open Source Database
Summit in Providence, Rhode Island on September 25, 2001.
Support for OGC functions has improved,
with lots of the easier ones added. And most exciting: PostGIS can now
be used as a data source by the University
of Minnesota MapServer!
More information on how to do this will be forthcoming shortly!
Several new functions have been added,
most notably support for Well-Known Binary. Documentation is getting better
and there is a WKB example application. Some testing has been done and
retrieval speed on a million-tuple table with a GiST index for a small query
frame is under 0.1 seconds on our test machine. Looking very good!
This release is largely untested and
does not include data loading. The JDBC and documentation are pretty primitive
as well. Please try it and send feedback to the mailing list.
The PostGIS Team is pleased to release PostGIS 2.5.4.
The PostGIS Team is pleased to release the first beta of the upcoming PostGIS
3.2.0 release.
Best served with PostgreSQL 14. This version of PostGIS utilizes the faster GiST building support API introduced in PostgreSQL 14. If compiled with recently released GEOS 3.10.0 you can take advantage of improvements in ST_MakeValid and numerous speed improvements. This release also includes many additional functions and improvements for postgis_raster and postgis_topology extensions.
