The Canadian Space Agency overarching objectives in support of the GFOI Element 3:• To support our National Forest community (government, academic
and private sectors) • To enable end-users to exploit the large amount of SAR data that is
now or will soon be available in support of their programs for forest management, ecosystem protection, carbon accounting, etc.
• Focusing our investments• Supporting and providing access to missions that meet user
requirements• Investing in operationally focused science and ensuring transition
towards operationalisation • Going beyond the science into Societal benefits

Acquisitions over GFOI R&D Study Sites• Due to the commercial nature of the RADARSAT 2
mission, the CSA is restricted to supporting science related activities as identified and endorsed by the GFOI science framework under the Element 3.
• Mostly interested in the following topics:• Use of Synthetic Aperture RADAR (SAR) for the monitoring of
forest related attributes;• Interoperability and complementarity between SAR and optical
datasets;• SAR/SAR mission interoperability;• Development of SAR-based approaches, algorithms, and
methods that are viably sustainable to support local, regional, national, continental and global forest monitoring and carbon accounting .

New and Archive data over GFOI R&D Study Sites
• Unprocessed and “globally distributed” RADARSAT 1
archive of limited coherent use for forest monitoring – to assess;
• Archive collected under the FCT framework – documented in support slides;
• Willingness to develop dense time series over punctual sites to support key science and demonstration activities.

Data provision for R&D • The CSA express its willingness to contribute new RADARSAT 2 data in the
context of Element 3;• Moving from a SOAR-based data dissemination approach to an open
sharing process as defined within a potential data service element à la GEOGLAM – assuming a secured cloud computing and data repository environment;– Require a thorough a priori identification of image products and certification of data user
organizations and individuals;– Number of scenes and access is project dependant and is to be determined;
• Operating under background mission framework;• As a counterpart, we are assuming open sharing of ground data, methods,
and derived results; • No cost to users – all processing and data costs will be covered by CSA;• Data products and processing level to be agreed with PIs;• Open to a coordinated AO on GFOI key science questions.

• CSA contribution to GFOI science plan can generate better understanding on issues related to SAR only, SAR/SAR and SAR/Optical data interoperability.
• As such, it is expected that the key science requirements, articulated in the context of Element 3, represent the position of the Global federated community under GFOI.
• In this context, the CSA Earth Observation programs (for data, science and demonstration) will remain available to support innovative development of solutions.
• Data requests will need to comply to the Canadian Remote Sensing Space System Act (RSSSA) and underlying Master Agreement principles between the Crown and MDA
