Unfortunately there are no slides of the pgRouting part, except the one that says PGRouting Live Demos because Leo will only do live demos. He has no fear of his demos not working.
Side note, if you are on windows and use the PostGIS bundle, all the extensions listed in the PostGIS box of the spatial extensions diagram, as well as the pointcloud, pgRouting, and ogr_fdw are included in the bundle.
Things are shaping up nicely in PostGIS 2.2 development. We are going to hit feature freeze around June 30th 2015, and plan to ship late August or early September to be in line with PostgreSQL 9.5 release.
So far we have committed a couple of neat features most itemized in PostGIS 2.2 New Functions.
Many of the really sort after ones will require PostgreSQL 9.5 and GEOS 3.5. The geography measurement enhancements will require Proj 4.9.0+ to take advantage of.
Things I'd like to highlight and then later dedicate full-length articles in our BostonGIS Waiting for PostGIS 2.2 series once they've been stress tested.
In this exercise, we'll go thru installing PostgreSQL 9.3 on a CentOS 6 64-bit box. We'll cover upgrading in a later article. For the rest of this article, we'll go over configuring yum to use the PostgreSQL PGDG Yum repository found at http://yum.postgresql.org
, which has the latest and greatest of 9.3. It's been a while since we wrote step by step instructions for installing with Yum.
Note: PostGIS 2.1.2 release is eminent, so you might want to wait till we release and Yum is updated before you install/upgrade.
PostGIS 2.1 bundle for PostgreSQL 9.3 Windows is now available on StackBuilder for windows users. You will find both the 32-bit and 64-bit versions. The bundle includes the following features:
PostGIS 2.1 with extensions support for postgis (which has geometry/geography/raster), postgis_tiger_geocoder, and postgis_topology.
pgRouting 2.0.0 with extension support -- just do CREATE EXTENSION pgRouting
address_standardizer, which is needed for better tiger geocoding normalizing. Installed with CREATE EXTENSION address_standardizer
One thing that is different with this packaging is that we are no longer providing a template_postgis database. However if you want your database created for you,
you can check the Create spatial database option which will create a regular old database with all the packaged extensions under the sun created for you.
PostgreSQL 9.3 came out today and we are excited to start using the new features. PostGIS 2.1.0 came out about 2 weeks ago and pgRouting just cut the RC 3 release. For windows PostGIS users who are impatient to try the new suite, binaries
can be found on the Unreleased versions of PostGIS.net windows page.
We are planning an official release sometime probably next week on StackBuilder. We are waiting for release of pgRouting 2.0 before we do which should be out next week. This new 2.1 release will be dubbed the PostGIS 2.1 Bundle since it will have more than just PostGIS. It will include postgis extensions (postgis which includes geometry,raster, geography) , postgis_topology, postgis_tiger_geocoder), address_standardizer extension (a companion to tiger geocoder), and pgRouting 2.0.
For those people running PostGIS 2.0 and PostgreSQL 9.0+, especially (raster and geography) users, I highly recommend you jump to PostGIS 2.1. PostGIS 2.1 is a soft upgrade from 2.0. For raster there are enormous speed improvements and new functions. The ones we are most excited about in raster are the much much much faster ST_Clip and ST_Union functions (which now does multi-band in addition to being faster). These two functions are highly important since they are generally the first step in many raster workflows. Geography has speed improvements for point in poly and a ST_Segmentize function done on the spheroid (important for long range). Geometry has a couple of new functions. The Enhanced 3D functionality provided by SFCGAL is brand new and probably won't be distributed by many package maintainers until PostGIS 2.2 where it will garner a few more features and stability improvements.
We've got experimental pgRouting windows binaries available for windows PostgreSQL 9.2 32-bit and 64-bit for pgRouting 1.0.7 development branch. More details on our Boston GIS blog page.
The final versions we plan to release with upcoming PostGIS 2.1 PostgreSQL 9.2 on stackbuilder as part of the PostGIS install. Barring no difficulties we'll also have experimental binaries for PostgreSQL 9.3 releases once 9.3 reaches beta.
This version and upcoming pgRouting versions support the PostgreSQL extension model, so if you have postgis already installed, its just an additonal simple step:
