IDELIX Software Inc. and Offshore Systems International Ltd. Announce Teaming Partnership
PDT to be integrated into OSI’s client-side tools to further enhance data interpretation and value

April 8, 2005 - VANCOUVER, BC - IDELIX Software Inc. and Offshore Systems International Ltd. (OSI) announced today the signing of a teaming agreement to support the integration of Pliable Display Technology (PDT) by IDELIX into OSI command and control solutions. PDT will be used to enhance geographic situational awareness within OSI products deployed at the strategic, operational and tactical levels.

"The partnership between IDELIX and OSI has been strongly customer driven," stated Andrew Carniel, OSI Vice-President, Business Development. "As live track and sensor information from sources such as UAVs becomes more accessible, the need for advanced visualization technologies to combat information overload and perform tasks such as change detection is increasing. Integrating PDT into OSI’s client-side tools will increase situational awareness capability for the defence and intelligence community. We believe that PDT is a great enhancement to our COP products."

By combining the advanced server offerings of OSI with the advanced visualization capabilities of IDELIX, these companies will supply the defence community with a unique, cutting edge client/server solution. Customers will be able to quickly access various sources of geospatial data from the OSI servers and use the PDT lens to perform continuous local resolution changes that will result in the magnification of detailed information without loss of the contextual data surroundings.

OSI is a pioneer in geospatial-intelligence and is the world-leading supplier of advanced naval electronic chart systems for navigation and situational awareness. Their product offering includes COP-IDS®, Common Operating Picture – Image Display Server. COP-IDS® by OSI facilitates the efficient and accurate integration of information from a variety of geospatial data sources - such as land maps, nautical charts, photo imagery, and special military information - into a single, fused display.

IDELIX specializes in information visualization solutions, and has developed an advanced user interface component called Pliable Display Technology (PDT). PDT is a "focus+context" lens interface that can be integrated into a variety of geospatial-intelligence and defence applications to provide a unique combination of precision, speed, data fusion and improved situational awareness to intelligence analysts, command and control and first responders.

OSI customers include naval fleets such as the Royal Australian Navy, Canadian Navy, Royal Navy, Royal Danish Navy, Portuguese Navy and Royal New Zealand Navy. The company also works closely with other military organizations and defence contractors internationally.

"PDT is a complementary technology to OSI’s COP-IDS® solutions and will provide OSI customers with superior situational awareness and data analysis capabilities," remarked Bijan Sanii, CEO of IDELIX Software Inc. "OSI is a recognized leader in the geospatial-intelligence market and we are pleased to be working with them to integrate our technology as part of their industry leading solutions."

In addition to commercial partner projects, IDELIX has also participated in geospatial-intelligence programs for various agencies including Natural Resources Canada (GeoConnections), Defence Research & Development Canada (Defence Industry Research Program), and the National Geospatial-Intelligence Agency’s (NGA) InnoVision and Enterprise Directorates.

IDELIX is exhibiting at CANSEC 2005, presenting Pliable Display Technology in applications from other commercial partners such as ITT Industries Space Systems, Paragon Imaging, and Black Coral Inc. CANSEC 2005, being held April 14-15 in Ottawa, Ontario, is the premier event for the Canadian defence industry, bringing together government, commercial, and military leaders with leading suppliers and industry experts. Attendees are invited to IDELIX booth #95 for an interactive demonstration of PDT.
