Oxford Visual Geosociences Ltd. Innovates Geological, Geochemical and Geophysical Discovery with Data Visualization Technology from Advanced Visual Systems

(Waltham, MA. - February 04, 2004) - AVS/Express, a comprehensive data visualization toolset from Advanced Visual Systems, has enabled Oxford Visual Systems Ltd., a leader in earth science data analysis, to develop decision-enhancing 3D graphics in its acclaimed GeoExpress software. The integration of Oxford Visual Systems' interpretation software with AVS data visualization technology has produced one of the sectors most profound tools for interactive visualization, research and project analysis of geological, geochemical and geophysical data. Examples of AVS/Express visualizations as featured in GeoExpress can be found at www.avs.com/igm/.

Oxford Visual Systems was formed in 1999 to develop ground-breaking solutions to the problems earth scientists face when analyzing and presenting complex datasets from a variety of sources. GeoExpress, the company's first commercial product was born from this philosophy and has utilized AVS/Express as the visualization engine since its initial release.

As a direct result of the AVS-rendered visualizations, users can interactively explore a wide range of domain-specific data formats on all Microsoft Windows platforms and quickly reach conclusions that would otherwise require extensive procedures on more expensive and complex systems. Additionally, AVS/Express enables the development of highly functional data readers and writers, allowing seamless data handling and eliminating the need for the creation and management of secondary databases.

According to Frank Arnott, Technical Director of Oxford Visual Systems, AVS/Express has enabled us to provide our users with an exceptional degree of insight to the many complexities of earth science data. Its powerful development methodology, rich visualization techniques and dynamic performance on the PC platform have provided Oxford Visual Systems with a solid foundation for our product strategy.²

AVS/Express enables rapid, object-oriented development of rich and highly interactive scientific and technical data visualizations for Digital, HP, IBM, SGI, Sun and Windows systems. Now in its seventh year of release, AVS/Express is widely considered the world's most popular software in scientific, academic and technical deployment. Designed for use by users with either no or highly advanced programming skills, AVS/Express is offered in several editions that exploit nearly every contemporary or legacy data format and can be deployed in a wide range of configurations.
