Tentatively around noon tomorrow, Thursday the 8th, near the Moscone center. Just an informal chat and a great opportunity to meet other users. Please email ak+meetup@openplans.org if you’re interested and I’ll be in touch with the details.

Also email me if you’re going to Where 2.0, we’ll try do something similar there as well.

Also, if you are a faithful reader of this blog, you’ll notice that Fernando Quadro often paraphrases some of our posts in Portuguese. There is a GeoServer mailing list in Portuguese as well. Earlier this month, the GeoServer website was “slashdotted” by Slashdot Japan regarding a company which is using OpenLayers, GeoServer, and GeoWebCache.

We currently have local translations for our web interface in Japanese, Chinese, French, German, Portuguese, and Spanish. We’re always looking for people to write more localizations as well (please see our website for information on how to localize GeoServer). We’re eventually looking to have the core of our documentation translated as well.

This is all very promising, as it shows that the need for an open-source mapping framework is a worldwide desire, transcending the boundaries of nation and language. We have set up a page denoting these international resources. If you know of other GeoServer blogs, mailing lists, or other websites that we may not be aware of, please add them to that page, as we would love to know about them.

The quick answer: yes!

GeoServer is built entirely on Java. Therefore, it can run on any hardware supported by Sun’s Java Runtime Environment. Unlike compiled languages, like C++, as long as the JRE supports the architecture, GeoServer can come along for the ride. Happily, 64 bit support exists in Java. So without any redesign or recompiling on our part, GeoServer can be run on 64 bit systems. That’s points for Java!

However, there are some caveats. Sun’s 64 bit JRE has been known be a bit buggier than their 32 bit version, which could be of concern in a production environment. Also, and probably related, performance takes a small hit with 64 bit (on the order of a few percent). Although there will be more discussion here later about performance tips, this seems like as good a place as any to mention that if performance is an issue on your system, we recommend that you look at updating your JRE to the latest version, if you can. Version 1.5 is much faster than 1.4, and version 1.6 appears to be roughly twice as fast as 1.5 in the context of running GeoServer. So, if you are moving to 64 bit but can’t afford the performance hit, you may want to look at updating your Java version as well.

Moving to 64 bit doesn’t need to be an either/or situation either. Our servers here (all 64 bit) are running both 32 bit and 64 bit Java instances, with few difficulties. Your mileage may vary. And of course, the big advantage of 64 bit is the ability to access more than 4 GB of RAM. This may not be an issue in your environment now, but if history is any guide, it will be eventually.

For more information on running GeoServer in a production environment, please see this guide.

Many software companies are at pains to inform the community when they offer 64 bit support. We have never explicitly mentioned this feature before because it has been offered from the beginning. We can’t take credit for the work, but we can surely enjoy the perks.

Along the way I learned that there have been some issues with JPEG and metatiling, and consequently GeoWebCache now falls back to Java 2D (instead of JAI) when dealing with those. Note that URLs used in GWC, and a few configuration parameters, have changed since the previous version.

One of the more visible additions is support for watermarking. People have been asking for this for some time, so thanks to GeoSolutions for implementing it. Also, coverage reprojection now works much better. Thanks to Martin Desruisseaux of Geomatys for the continued support on the GeoServer CRS subsystem. KML generation has been optimized (faster, less memory consumption) especially when dealing with large geometries. GeoServer supports so many projections natively, but that can have its downsides, namely when certain clients aren’t prepared for the size of the capabilities document! Now the SRS list can be limited in the WMS capabilities. Special thanks to Gabriel Roldán for the above two features.

You can view the 1.6.3 changelog for details, and download from geoserver.org. Thanks to the community for continually improving GeoServer. Please continue to submit those bug reports and feature requests.

GeoTools 2.5.x contains the new feature model, which should be able to handle the full complexity of GML and any other model that architects may throw at us.  There is still a lot of work to fully incorporate it in to GeoServer, but this alpha release does represent the first step forward towards that goal.

You can get 1.7.0-alpha1 on the Latest download page, while 1.6.2 is still available on the Stable page.

I am new to the GIS world. Well, not entirely. I’ve been an avid map fan since I was a wee lad, and to this day I own a small but extensive collection of Rand McNally Road Atlases. Fast forward the tape a bit, and here I am at The Open Planning Project, as an Outreach Engineer for GeoServer. However, despite some years of working in technical fields and some more years of ogling nice-looking maps, I must confess that I was and still am, shall we say, a novice to the technology surrounding GIS.

Here at TOPP, I see myself as a facilitator between those who use GeoServer, those who code/develop for it, and those who are somewhere in between. That said, I’ve still needed to bootstrap myself into being versed in the terminology. So, I picked up “GIS for Web Developers” by Scott Davis. Since then I have thumbed through a few other books and a fair chunk of online information, but by far, this has been the most helpful in getting me started.

The book follows a fairly straightforward arc, starting with a discussion of vectors and rasters. Two of my initial questions were answered quickly. The first was “where does all this data come from?” and the second, “what exactly is the data, anyway?” These may seem trivial, but it’s of course very hard to not see as obvious things that one works with as a matter of routine. (I can recall being very perplexed when I was first introduced to the Web, when trying to figure out the URL. Where was it going? What was it doing?) Although I can’t create a Shapefile out of thin air now (Adobe Illustrator for some reason doesn’t have it in its Export menu) I know that I can probably find what I need either from government websites or a small but growing community of neogeographers. As for what’s contained in the data, the answer is “a gratifyingly large amount of useful info”. The book covers Shapefiles, PostGIS databases, and other standard formats of the trade.

The discussion makes a sharp turn and delves into command-line utilities for editing and querying data inside spatial databases. Perhaps it was my background, but I thought that this topic might have sat more comfortably towards the back of the book, as it’s good information, but with a much steeper learning curve than what came before it. After delving very deep into the OGC web services, the book ends with a “Final Exam” of the complete process from non-geocoded data to spatial database to web browser. If one can follow the last chapter, one understands the relevant concepts. I think I’m nearly there.

One of the most beneficial aspects of the book was the clear definitions of terms, as the meanings of, say, DataStore and FeatureType were not intrinsically obvious to me. It was also quite nice to see GeoServer represented so favorably in the book, both from a practical point of view and as well from a root-for-the -home-team sort of way. But ESRI’s ArcExplorer is given as much treatment as, say, MapBuilder, which is nice for comparison’s sake. I have yet to spend too much time on anything past GeoServer and OpenLayers, but that’ll change in time, I’m sure.

Personally, I wished the book had delved more quantitatively into projections. However, I recognize that my interest lies mainly in the mathematics, and the tools that people have created shield the user from some of the more unseemly calculations. My coworkers have consistently said, “you don’t need to know any of that stuff,” which may in fact be true, but keeping projections as a black box isn’t quite in the spirit of the book. It’s a minor gripe, though.

All in all, I found this a great book with which to get started. While not trying to hide from the jargon, the reader isn’t bogged down with so much granularity that the plot is lost. That’s a sweet spot that most technical books miss. I’m no expert, and won’t be for a while, but at least I feel like I know what questions to ask. And knowing how to ask the right questions is so much more difficult than finding the answers.
