Color blending and compositing implemented for GeoServer 2.7

Blog ‐ Posted on 02.02.2015 by Andrea Aime

Dear Readers, in this post we want to introduce a new mapping ability available in the GeoServer 2.7.x series: color blending and compositing. The notion of color blending and compositing has been borrowed from the SVG specification, and it's commonly available in image manipulation programs such as Gimp/Photoshop, and has been available, with different types of limitations, in open source GIS software MapServer, QGis and Mapnik. GeoServer own implementation is sort of a sum of the above software abilities, in that it provides both Porter-Duff compositing, useful for masking, color blending, great to more naturally blend multiple colored levels, and base compositing layers, very important to...

Protecting GeoServer with CAS in an Enterprise environment

Blog ‐ Posted on 20.01.2015 by simone giannecchini

Dear Readers, in this post we will show a practical use case taking advantages from the GeoServer CAS authentication provider extension. A small introduction first. As you may already know, GeoServer ships with an highly configurable security subsystem based on Spring Security. This has been completely re-engineered, providing a more secure and flexible authentication framework. We are not going to provide techincal details of the security framework in this blog, but it is worth to highlight few features which are quite interesting.

UK GEMINI 2.2 schema plugin for GeoNetwork

Blog ‐ Posted on 13.01.2015 by Emanuele Tajariol

Dear all, We have released in the GeoNetwork official repository a schema plugin that deals with the UK GEMINI (GEo-spatial Metadata INteroperability INitiative) v2.2. UK GEMINI v2.2 is an application profile of ISO19139, which follows the  metadatarequirements for  the EU INSPIRE Directive. You can find the standard specifications here. The schema plugin mechanism enables GeoNetwork to edit, visualise and disseminate metadata expressed in any format, once you provide XSD schemas for the format, and a set of XSL files which tell GeoNetwork how the metadata document should be processed. GeoNetwork was the reference metadata editor for GEMINI v2.1, and a...
