Support for polymorphism is included in Geoserver 2.0.2. Why do we need polymorphism support in app-schema? Some complex attributes are polymorphic by nature, which means they can have different types for different features. Before polymorphism was supported...

Styling map layers in GeoServer can be challenging. While there are some ways to craft map layers without ever needing to look at Styled Layer Descriptor (SLD) code, there are some who don’t want an intermediary and want to code with SLD directly...

When designing a map, sometimes you want to render something that is related to the geometries you have at hand, but which is not specifically the geometries themselves. Maybe you want to highlight the end of a line, create a drop shadow effect, or make...

Ever had the need to format some text in SLD, or to perform complex filter in WFS, and noticed that the basic elements of the OGC Filter specification left you wanting for more?
If so, welcome to the club. One thing few people know is that both SLD and...

Here’s a quick announcement for all those who understand the above: GeoServer now has a Spanish language users mailing list! Created and moderated by core GeoServer developer Gabriel Roldán, the mailing list is a resource for those who would like assistance...

Here’s a neat trick for those working with road maps that want to indicate traffic direction by way of appropriately pointed arrows. With text symbolizers using font characters, this is actually a snap, provided your data includes information about...

Admit it. You love visualizing data. Mere tables do nothing for you, but the minute you can turn that into a map (or a graph or chart), information comes alive.
I was recently turned on to Swivel, a website that allows you to upload, visualize, and share...

OpenStreetMap is a free and editable map of the world. Founded in 2004 in the United Kingdom in response to the need for a free geospatial data source, it is a community-driven project, allowing for anyone to edit and contribute information. It has since...

Improvements to GeoServer are being made all the time, but to the average user, not all improvements are immediately discernible. However, recently a new feature has been added to GeoServer’s rendering algorithms, and all I can say is “wow.” I am...

A new post on the Raster Symbolizer tips & tricks, this time I am going to show how to build an RGB image using 8 bits or unsigned 16 bits multi band coverages.
I have been playing lately with some remote sensing data for the geoSDI project specifically...

In our previous post on dynamic symbolizers, we saw how we can generate dynamic external symbolizers based on feature attributes using only a simple style (SLD).
Today we’ll see two other features of dynamic symbolizers, namely: using decorative...

The GeoServer team is happy to announce the release of GeoServer 1.7.1!
The biggest improvement in this release is better Google Earth support. Using revamped KML output (known as the KML “reflector”) GeoServer can now output vector super...

When GeoServer 1.7.0 was released in October of 2008, it included some new features that many people might find useful. One of those new features is support for dynamic symbolizers.
Dynamic symbolizers, which originated from a GeoTools styling subsystem...

I am going to bother for a few mins in order to show a few things about the raster symbolizer implementation that has landed on 1.7. Ideally this should the first of a series of more posts, but I can’t guarantee on that :-).
Anyway, today I have...
