SAR – Game Changer for Forest Monitoring
Since the first SDCG at CSA (2012), Canada initiated the development of a: Coherent, systematic, interoperable and complementary C-band data set for forest monitoring Interoperable with Sentinel Complementary to optical and other SAR data sets (P-, L- , S- , X-, band) This new C-band dataset (integrating R-2 and Sentinel 1 and soon RCM) brings new level of information Integrated SAR-derived information still to be discovered, remain unexploited We need good science We need systematic feedback loop with the science teams GFOI R&D and Capacity Building are CRITICAL to the success of GFOI

CSA RADARSAT 2 Data provision procedures
Data to be made available through a collaborative sharing procedure (Multi-User Request Format) Requires 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.

Product Description Extra-Fine
The Extra-Fine Resolution Beam Mode nominally provides similar swath width and incidence angle coverage as the Wide Fine Beam Mode, at even finer resolutions, but with higher data compression ratios and noise levels. The four Extra-Fine beams provide coverage of swaths of approximately 160 km, 124 km, 120 km and 108 km in width respectively, and collectively span a total incidence angle range from 22 to 49 degrees. This beam mode also offers additional optional processing parameter selections that allow for reduced-bandwidth single-look products, 4-look, and 28-look products. Extra-Fine Beam Mode products can only be generated in a single polarization, which can be either a linear co-polarization (HH or VV) or a linear cross-polarization (HV or VH). Fine Quad Polarization The Fine Quad Polarization Beam Mode provides full polarimetric imaging with the same spatial resolution as the Fine Resolution Beam Mode. Fine Quad Polarization Beam Mode products with swath widths of approximately 25 km can be obtained covering any area within the region from an incidence angle of 18 degrees to at least 49 degrees. Multi-Look Fine The Multi-Look Fine Resolution Beam Mode covers the same swaths as the Fine Resolution Beam Mode. Products with multiple looks in range and azimuth are generated at approximately the same spatial resolution as Fine Resolution Beam mode products, but with multiple looks and therefore improved radiometric resolution. Single look products are generated at finer spatial resolutions than Fine Resolution Beam Mode products. In order to obtain the multiple looks without a reduction in swath width, this beam mode operates with higher data acquisition rates and noise levels than Fine Resolution Beam Mode. Like in the Fine Resolution Beam Mode, nine physical beams are available to cover the incidence angle range from 30 to 50 degrees, and additional near and/or far range swath positioning choices are available to provide additional overlap. Multi-Look Fine Resolution Beam Mode products can only be generated in a single polarization, which can be either a linear co-polarization (HH or VV) or a linear cross-polarization (HV or VH).. Wide Fine Quad Polarization The Wide Fine Quad Polarization Beam Mode operates the same way as the Fine Quad Polarization Beam Mode but with higher data acquisition rates, and offers a wider swath of approximately 50 km at equivalent spatial resolution. Twenty one beams are available covering any area from 18 degrees to 42 degrees, ensuring overlaps of about 50% between adjacent swaths. SDCG-8 DLR, Bonn, Germany September 23rd-25th 2015
