The integration of high dimensional geo-visualization, geo-data management, geo-process modeling and computation, geospatial analysis, and geo-collaboration is a trend in GIScience. The technical platform that matches the trend forms a new framework unlike that of GIS and is conceptualized in this paper as a collaborative virtual geographic environment (CVGE). This paper focuses on two key issu...

The GEO 600 gravitational wave detector located near Hannover in Germany is part of the LSC network of gravitational wave observatories. Since January 2006 the GEO 600 detector has participated in the S5 LSC science run and acquired sensitive and well-characterized science data with a high duty cycle. Until 1 October 2007, 415 days of science data with an average peak sensitivity of better than...

Geo-tags provide an essential support for organizing and retrieving the rapidly growing online video contents captured by users and shared online. Videos present an unique opportunity for automatic geo-tagging as they combine multiple information sources, i.e., textual metadata, visual and audio cues. This report highlights various approaches (data-driven, semantic technology-based, and graphic...
