Canadian Space-based Assets • RADARSAT series – Active sensor – ideal for polar imaging Canadian Space-based Assets • RADARSAT series – Active sensor – ideal for polar imaging activities – Flexible imaging configuration – high and low res. , narrow and synoptic coverage, land water surface – High frequency of revisit – VERY RICH Polar archive (North and South) • Other assets – Scisat – Anik F 2 • Envisat ASAR and Meris – within the data policy framework as agreed with ESA

Canadian Space-based Assets • RADARSAT series – RADARSAT 1 - 11+ year archive – Canadian Space-based Assets • RADARSAT series – RADARSAT 1 - 11+ year archive – RADARSAT 1 - New acquisitions to enhance the value of the archive – Satellite available until March 2009 – RADARSAT 2 – Use the Canadian Government data allocation for science activities under IPY – RADARSAT Constellation Mission – IPY Legacy • Focus on National and International consultation and coordination

RADARSAT 1 Archive • Archive is RADARSAT 1 Archive • Archive is "information rich" – as it was constituted by coherent data acquisition plans (multi-date, varying geometry, varying coverage, seasonally coherent) • Significant repeat coverage allows unique change detection, thematic analysis opportunity • Complimentary to existing data – optical framework, mapping databases, etc.

RADARSAT 1 Background Missions RADARSAT 1 Background Missions

Arctic Science Archive Processing (ASAP) • To increase the use of RADARSAT 1 archive Arctic Science Archive Processing (ASAP) • To increase the use of RADARSAT 1 archive under the IPY Framework and other national priorities • Focus on National and Int'l consultation process • Initiate the processing of a significant portion of the RADARSAT-1 Canadian archive - received through direct reception at GSS and PASS or recorded data that was played back in Canada • Preparation for RADARSAT-2 era; Canada maintaining leading position in space-based SAR remote sensing

MAMM 2, …) • Polar Snapshots – Sea ice min and max series (2003 – 20…) • Canadian Arctic Land masses (In. SAR) • Other supersites identified by the Canadian and Int'l communities • And others… • New data: Radarsat 1 and Radarsat 2 data products • Consultation for the definition of thematically intelligent archive for polar regions

Coordination • Ensure collaboration to/for: – Harmonize processing for RADARSAT 1 archive (i. e. Coordination • Ensure collaboration to/for: – Harmonize processing for RADARSAT 1 archive (i. e. Alaska Satellite Facilities, KSAT) – Acquisition and planning coordination – Through National and International networks – Open data policy for science activities • Support the objective of WMO Space Task Group

Challenges • Data policy • Distribution framework for Radarsat-1: Commercial • Radarsat-2 owned and Challenges • Data policy • Distribution framework for Radarsat-1: Commercial • Radarsat-2 owned and operated by MDA – use of Canadian Government Data Allocation • Restricted to science use – NO operations supported • Costs related to the data processing in the archive • Broad dissemination and return on investment

Summary • RADARSAT data & products are available, contributing to Canadian and International goals Summary • RADARSAT data & products are available, contributing to Canadian and International goals for Polar sustainability, resources management, sovereignty, and science • Canadian EO satellite coordinated with global goals and data demand supply. • National and Int'l consultation to guide strategic development of RSAT dataset and optimal use of its resources • Coordination with other Information Network managers and linkages
