The OSGEO C-Like tribe of which PostGIS is a member of had a nice code sprint in Montreal this month where Paul nailed down most of the issues he was having with 3D spatial index support so looks like we can look forward to that. Jeff Adams from Azavea took care of
quite a few shapefile loader issues (shp2pgsql), and also added in many regression tests for shp2pgsql that we were sorely missing. Pierre Racine (University of Laval), David Zwarg (Azavea), and Jorge Arévalo (Deimos Space)
(working remotely but definitely pitching in a lot) worked out some raster memory issues and improving ST_MapAlgebra. Olivier Courtin ironing out 3D serialization and handling of solids.
We haven't called feature freeze yet on PostGIS 2.0, but I would say most of the functionality you can expect is in place, but will undergo some more polishing. We aren't quite as disciplined as the PostgreSQL core group, but then again
we are a much smaller group so can afford to be less disciplined. Such a discipline
early on I think would be more stiffling than beneficial. It's still too early to tell if KNN GIST will make it, but sadly it's no where to be seen
yet, much to the chagrin of some.
Raster is really kicking dust, people jumping in to contribute, memory leaks and so forth being macheted down. Some people already using it and we haven't even released 2.0 yet. That has been pretty
exciting to see take shape and the excitement around it.
I'm also happy to see a lot of people on the User's list testing our Windows experimental builds. If only there was a windows build of PostgreSQL 9.1 newer than Alpha 1. We've been hesitant to build for newer since PostGIS we compile
against the newer alphas gives strange errors on certain functions when used with 9.1 Alpha 1 VC builds. No we still don't have 64-bit Windows builds of PostGIS, but hope to focus on that after the book is completed. I think we will end up going the mingW64 route
since VC sounds like it would be a great deal more effort with our current PostGIS toolchain.
Topology made a surprise showing as well with many many improvements from Sandro Santilli and Andrea Peri. Sandro also discovered the term 3D Topology.
Once he calms down from the frightful thought, he may actually start working on that for the
While 2D geometry and GIS has been fun, Augmenting that experience with 3D has been for a long time on my dream path. A true Post-GIS adventure.
What comes after GIS? virtual space, the frontier you make of it. At least for me anyway.
I'm also looking forward to getting back at least a tincy bit to my engineering roots.
What about PostGIS in Action book?
First of all I'm happy to report that we are closer to having book out, hmm how long have I been saying that? I am sad to report this has gone on for what feels like an eternity and I'm hoping in the end it will all be well worth the wait.
It could be any day
now (so we are told) for the final PDF E-book version, then a week or so after for the hard-copy (which has already started printing), and then not quite sure when the e-Pub, Mobi
and other e-Book versions become available, but would guess a month or so after.
We got the final proof of the front and back cover, and all I can say is Ain't she pretty. She isn't quite the baby elepant with a unicorn horn and infrared eyes I hoped for, but she'll do this time around..
