Here's the recent open source / open data geonews in batch mode.
I'm abroad this week, expect return to normal geonews coverage next week, thank you for your patience.
Slashdot discusses a story named Why Hasn't 3D Taken Off For the Web?
We mentioned WebGL often lately, with many geospatial web tools betting on it.
Here's the recent geonews in batch mode.

Every year, NORAD tracks Santa as he makes his trip around the globe on Christmas Eve. The NORAD Tracks Santa program is popular, receiving 19 million unique visitors last holiday season.
This year, as part of the NORAD Tracks Santa team, Analytical Graphics, Inc. used Cesium, an open-source WebGL virtual globe, to build a 3D web map for visualizing Santa’s location. The app goes live on December 24th at www.noradsanta.org. In the meantime, there is a tech write-up with screenshots showing the global terrain, imagery, and water. There are also instructions for making sure your computer will be able to run the app.
Here's the recent FOSS4G geonews.
In open source software updates:
In the everything else category:
The WebGL Camp provides WebGL developers a forum to present updates on their latest projects and frameworks. After five WebGL Camps in the USA, WebGL Camp is now coming to Europe being hosted by the University of Applied Sciences and Arts Northwestern Switzerland.
The agenda is online now and there are many geo visualization topics, for example Nokia 3D Maps, 3D building visualization, stereovision mobile mapping, CZML: the JSON schema for describing dynamic scenes in virtual globes (Cesium Globe), the OpenWebGlobe SDK for creating new virtual globe applications, and much more.

There is a new project on Github that has made a 3D view for OpenLayers! It integrates AGI's new open source WebGL globe (Cesium) and uses the OpenLayers drawing & navigation tools to interact with the globe. Support for WMS layers and feature importing are next on the to-do list.
A live demo can be found here:
The source code is available here.
At last week's 3D GeoInfo conference, I learned about the open source Glob3 3D GIS and Glob3 Mobile 3D virtual globe.
There isn't much on the sourceforge website: "glob3 is an open source 3D GIS multiplatform framework written in java with a very non restrictive license and advanced features."
The apps for iOS and Android are free.
I was at the 3D GeoInfo 2012 conference last week and I learned about the DB4GeO / DB3D open source geospatial database, which is a Java object-oriented database focusing on 3D data. It supports CityGML, has a RESTful API and has its own WebGL visualization tool.
Since I failed to find much about it on the web other than the GitHub page (it seems the code wasn't synchronized for a while), let me serve you the abstract [pdf] of last week's presentation: "The analysis of complex 3D data is a central task for many problems in the geo- and engineering sciences. Examples are the analysis of natural events such as mass movements and volcano eruptions as well as 3D city planning and the computation of 3D models from point cloud data generated by terrestrial laser scanning for 3D data analysis in various domains. The volume of these data is growing from year to year. However, there is no geo-database management system on the market yet that efficiently supports complex 3D mass data, although prototypical 3D geo-database management systems are ready to support such challenging 3D applications. In this contribution we describe how we reply to these requirements advancing DB4GeO, our 3D/4D geo-database architecture. The system architecture and support for geometric, topological and temporal data are presented in detail. Besides the new spatio-temporal object model, we introduce new ideas and implementations of DB4GeO such as the support of GML data and the new WebGL 3D interface. The latter enables the direct visualization of 3D database query results by a standard web browser without installing additional software. Examples for 3D database queries and their visualizations with the new WebGL interface are demonstrated. Finally, we give an outlook on our future work. Further extensions of DB4GeO and the support for the data management for collaborative subway track planning are discussed."
I'd like to see the differences between PostGIS vs DB4GeO features in regards to 3D geodata. Is DB4GeO more and a playground for researchers?
The demo version of a potential 3D Viewer for geo.admin.ch - the geo-portal of the Swiss Confederation - is online at http://swiss3d.openwebglobe.org until July 31, 2012.
The 3D Viewer is based on the open source globe “OpenWebGlobe” using WebGL.
The scene convers entire Switzerland and is based on high resolution data from swisstopo: SWISSIMAGE, DHM25 and swissBOUNDARIES3D as well as extracts from swissBUILDINGS3D.
In addition, textured 3D objects from FHNW Muttenz and EPFL Lausanne are available. Outside the area with high-resolution data, Blue Marble from “NASA’s Earth Observatory” is used.
The total amount of texture and geometry data exceeds 2 TB and is being handled using the cloud from Amazon Web Services.
This demo has been developed by FHNW - University of Applied Sciences and Arts Northwestern Switzerland, camptocamp SA, the Federal Office of Topography, Switzerland, and geo.admin.ch.
