• Rudi Hochmeister has contributed a patches to our logging system to simplify debugging and to fix a number of issues in our developer documentation.
• Gianni Barrotta, Andrea Di Nora, and Pietro Arena have contributed a number of new WPS processes to the project.
• Robert Coup has identified inconsistencies in the handling of URLs in the KML and GeoRSS output formats and has contributed patches to bring those in line with the rest of the code base.
• Matt Bertrand has added support for the definition of character set during shapefile uploads and associated testing.

Contributions like these help keep GeoServer responsive to the needs of our community and allow us to continue providing a stable and useful product. Thank you! Thanks also go to LISAsoft for sponsoring this release. Please download GeoServer 2.1.1, try it out, and provide feedback on the mailing list. Your feedback helps GeoServer to continue to improve.

As previously mentioned, GeoServer now provides support for Oracle Georaster, custom database layouts for image data and polymorphism.

Have you ever wondered what geographical area an EPSG code covers? A new feature has been added to showcase the different projections visually, by showing a map of the projection’s area of validity in the same CRS. Here are three examples of this: EPSG:2964, EPSG:3032, EPSG:22184.

To add to this, we have also added a default style preview in the layer publishing configuration.

The rendering subsystem has been improved to include parameter substitution, meaning you can pass parameters down from a GetMap request into your SLD for dynamic styling purposes.

The ability to do geometry transformations, included in GeoServer 2.0.1 without much fanfare, now has been completely documented.

Building image pyramids just got easier: gone are the times where you had to manually build each level mosaic and configure the main property file by hand. The current pyramid extension can do this for you provided it is given a suitably configured directory set. See the pyramid tutorial for more details.

Finally, this release of GeoServer implements the GetStyles optional WMS method allowing a user to retrieve the definition of all styles attached to a specific WMS layer, see the following link for an example:
http://demo.opengeo.org/geoserver/wms?request=GetStyles&layers=topp:states&service=wms&version=1.1.0

Thanks to everyone who have worked hard over the past few months adding features and fixing bugs, in order to make this release happen. As usual, we encourage you to download, try it out, and provide feedback on the users mailing list.

Supporting a project such as GeoServer requires a great investment of time and resources. Organizations that support it are faced with the problem of finding funding. As founder of my own company, I often find myself in the position to seek funding for supporting GeoServer and I obviously tend to prefer large contracts to small ones. This seems perfectly reasonable, however I do recognize that in the long run this approach may cause some missed opportunities. Large funding usually focuses on large developments, but they leave aside common glitches and bugs, i.e. isolated features that are not working properly or could be improved relatively easily. To counter this, supporting organizations must invest surplus money and resources from other contracts into tackling these problems, since it is difficult or inefficient to chase money to address each small issue separately.

As a specific example, I have lately seen people struggling to get the ImagePyramid extension working, and I know it would be relatively easy to improve things (in that it would not need a lot of funding) but none of our current clients needs this functionality, so the work never gets done.

With this in mind, I have come up with the following idea: once someone, be it a user or a support organization, recognizes an issue/missing feature that no one else wants or has funding to fix, we should try to describe the problem/feature somewhere (such as on this blog), provide a Point of Contact (POC) for the work and then ask the community for an Expression of Interest (EOI) to check whether there is enough momentum/desire to fix/implement. Perhaps the POC should write the proposal having already scoped out the work or maybe the scope should wait until we know that there is enough interest. Another topic where I would see some interest is in whether the process should be completely transparent or not regarding who gives the funding as well as who spends the funding gathered. I would be interested in feedback on all of these suggestions.

To test his idea, I would like to invite anyone who might be interested in providing a bit of funding to improve the support for the ImagePyramid extension in GeoServer to express your interest to me. Specifically, I am talking about automagic import from GDAL retile, improved stability and performance, and/or automagic pyramiding as a GeoServer/GeoTools utility.

Ciao, Simone.

The session will be held on Thursday 22nd October, late afternoon (specific time TBD). If you are attending FOSS4G 2009 (and you very much should), feel free to stop by in order to say hi and chat a bit with us.

See you there!

1. GeoServer was keeping all its configuration into memory
2. GeoServer was making use XML files to handle its internal configuration

Now a lot of work has been lately for the upcoming 2.0 version of GeoServer, to cope with point 2 above, however point 2 has not been touched yet.
If you use GeoServer the way we use it, with thousand of layers and with 10 to 100 new layers added daily (usually remote sensing data), you might agree with us that we need to:

1. Not load and keep the entire configuration in memory
2. Use a database to store the configuration

In a few words, we need to improve scalability and robustness while tring to not jeopardize performance, we need to be enterprise-ready.

At GeoSolutions we have decided to tackle this problems by implementing a new GeoServer internal catalog that leverages on Hibernate as its persistence engine and that would also not bring the whole configuration into memory. Our goal is to be able to support at least Postgis and Oracle as the target database, but as you know, many more are supported by Hibernate (spatialite wi  ontheradar as well).
The range of features that this work would open up is pretty wide, just think about using Hibernate distributed caching, simplified GeoServer replication, etc., etc.

The work is in progress, we have started to describe the details on the GeoServer wiki .
If you are interesting in supporting somehow (funding or human resources) this effort, please, drop me a few lines at simone.giannecchiniATgeo-solutions.it.
