Presentation Agenda l Introduction – Richard Rysak - ATIC n l Dr. Craig Coburn – University of Lethbridge n l 2 ATIC + SPOT Satellites – an Overview SPOT Imagery in Academic Setting Consortium Offer – Adam Minke - ATIC
Over 800 Active Satellites 3
ATIC - Alberta Terrestrial Imaging Centre l Joint venture between the University of Lethbridge & Iunctus Geomatics Corp. l Incorporated in mid-2005 Our mandate: l l 4 Develop the Canadian academic market for SPOT satellite data Applied research using remote sensing while working with end users to develop commercial products for managing natural resources and protecting the environment
Remote Sensing The science and art of obtaining information about an object, area, or phenomenon through the analysis of data acquired by a device that is not in contact with the object, area, or phenomenon under investigation. Remote sensing is an applied science which helps in understanding many activities such as forestry, land usage, agriculture, environmental protection, water management, etc. 5
Key Steps in Remote Sensing Receiving and Processing Sensor - Data Collection 6 Image Data Human/Computer - Analysis
SPOT Image Group - Overview l l l l 7 Operator of SPOT satellites and supplier of satellite data Based in Toulouse – France, founded in 1982 SPOT = Systeme Pour l’Observation de la Terre Ownership: CNES (French space agency), Aérospatiale Matra, IGN, governments of Belgium, Sweden, and Italy + private investors 200 employees Worldwide ground station network 8 distributors worldwide
Iunctus Geomatics l l l 8 Canadian/US Rights to distribute SPOT data since 2002 Ground Station on University of Lethbridge campus Infrastructure to process SPOT data in North America Focus on commercial markets via Telus Alliance Academic markets – sublicensed to ATIC’s academic prices for Canadian imagery substantially below commercial prices
