Accès et Utilisation de RADARSAT-2

1,668 views

Published on

L’Agence spatiale canadienne fournit de l’imagerie satellitaire aux différents ministères fédéraux depuis le lancement de RADARSAT-1 en 1995. Avec la venue de RADARSAT-2 en 2008, l’utilisation et des applications en Observation de la Terre ont fait un bond important au sein du Gouvernement du Canada. La raison de ce succès est liée principalement à l’accessibilité de la donnée. L’emphase sur les produits à valeur ajoutée est aussi un facteur important à considérer. Les prochaines générations de satellites telles que la Constellation RADARSAT seront une source accrue de données qui nécessitera une infrastructure géomatique importante afin de rendre disponible la donnée à un plus large public.

  • Negotiate agreements such as Memorandums of Understanding (MOU) and Letters of Understanding (LOU) with data users. Develop and implement programs and initiatives that optimize the utilization of data such as SOAR, GRIP, EOADP , background missions and barter opportunities with foreign space agencies. Negotiate revisions to the R2 Data Policy Review ( Schedules D1 and D2 ) MDA/CSA Quarterly Meeting (data confidentiality, scenes overlap deduction, NMSO…) Liaise with Government Users to plan for their RADARSAT-2 data utilization. Assist in resolving conflicts between Government Users. Make financial arrangements with Government Users for products and services not deducted from the government data allocation or provided for by the CSA and the cost of data processing; i.e. CPT Allocation billed by MDA Ensure the full and efficient utilization of the government data allocation credit Ensure that the data acquired through RADARSAT-2 is utilized to its full potential. RADARSAT-1 to be included in MDA-GSI processing contract for small requests. Annual MDA/GSI Business Plan Updates Follow up. Ensure effective liaison between Programs i.e. SOAR, EOADP and GRIP. Date
  • RADARSAT-1 – Examples of success stories One of the primary objectives was to provide SAR data to the Canadian Ice Service. Number of images used annually varied from and average of 4000 images per year in the early years to over 6000 images in 2007-08. Mosaics were produced for Canada, USA, Africa, Australia and Antarctica using mostly ScanSAR Narrow (50 m resolution). The CSA is member of the International Space and Major Disasters since 2000. RSAT-2 has provided 193 archive images and 268 NRT images … and much more RADARSAT-2 First image that was acquired was a Quad-Pol of extremely high quality. It was acquired only 4 days after Launch. Improved resolution of 3 meters All heritage beams are available in selective single or Dual polarization. Thunder Bay ScanSAR Narrow B with dual polarization (Transmit VV; Receive VH) Example of Freeman decomposition highlighting single bounce (blue) double bounce (red) and volume scattering (green). Complete Polarimetry with R-2 Quad-Pol Data offers much more than 4 images. Using Decomposition algorithms, polarimetric signatures or other types of tools allow to retrieve information that would difficult to get otherwise. The Advanced Polarimetry Workshop on Thursfay (by Ridha Touzi) will discuss tools and methods to get the most out of your polarimetric datasets. RCM - Better coverage and revisit period (next slide gives more details on similarities and differences)
  • RADARSAT-2 quad polarization products were used to compare vessel backscatter detection with ground truth measurements; assess the effect of incidence and azimuth angle on maritime vessel detection performance; assess the effect of ocean conditions on detection performance; assess the benefits of dual polarization and full polarimetry by comparing channel signatures and applying both coherent and non-coherent decompositions. Ocean studies included algorithm development to improve iceberg and ship detection; multi-polarization approaches for oil spills and vessels detection; and retrieval of winds from SAR data at different radar frequencies and polarizations (VV and HH).
  • SOAR supported studies to develop advanced polar sea ice mapping algorithms using high-resolution, multi-polarization/polarimetric data; to characterize sea ice classes; and to detect icebergs at the ice shelf/sea ice boundary. Ice applications also included determination of glacial motion variations by generating a series of interferograms; use of speckle tracking of fine and ultra-fine beam modes to produce the most accurate velocities; investigation of the radar backscatter response from dynamic sea ice geophysical and thermodynamic conditions in the spring melt period; and finally the study and mapping of Antarctic periglacial, glacial and geological structures. Arctic air temperatures have increased by as much as 5°C during the 20th century (IPCC 2007). Arctic ice caps have lost volume coincident with a general increase in temperature throughout the region. Models project that there will be a warming between 2.8°C and 4.6°C by the late 21st Century. This warming will have implications for glaciers (and glacier dynamics) within the Canadian Arctic.
  • Topics included generation of land cover maps in order to show diverse agriculture, natural areas, and urban areas using fully polarimetric data. Land use studies integrated exploration of the newly advanced radar and optical imageries for large area wildlife habitat mapping, including land cover classification and data fusion; generation of a tomographic dataset that will be used to develop interferometric tomography for both urban and natural environments. Topographic mapping projects also included 3D surface mapping; orthorectification and digital elevation models extraction. The vision of the global urban footprint using high resolution radar imagery!
  • Geology applications included the monitoring of mining induced surface deformation using repeat-orbit ultra-fine mode, using differential SAR interferometry and point-target based interferometric techniques; and also the use of SAR imagery for mineral exploration and resource management.
  • Cylindrical fuel storage tank Some storage tanks need a floating roof in addition to or in lieu of the fixed roof and structure. This floating roof rises and falls with the liquid level inside the tank, thereby decreasing the vapor space above the liquid level. Floating roofs are considered a safety requirement as well as a pollution prevention measure for many industries including petroleum refining. On the use of SAR High Resolution Spotlight data for Persistent Scatterers and Tomographic analysis Credit : Valentin Poncos (SOAR-E 5004) On the use of SAR High Resolution Spotlight data for Persistent Scatterers and Tomographic analysis Accurate height and displacement measurements of features on the ground In both urban and natural environments ground displacement is always present. By using RADARSAT-2, estimating building heights and monitoring ground displacement with millimeters accuracy is now possible. Figure 1 : High Resolution Spotlight mode Radarsat-2 image of the city centre of Edmonton (2x2 meters resolution).
  • 2 payloads - 2-panel SAR antenna and AIS Small bus; low mass (~ 1300 kg) Equal spacing in low orbit (~ 600 km)
  • During Phase A, the CSA formed the User and Science Team (U&amp;ST) to engage the end user departments and scientific community to ensure their user requirements would be addressed and captured as early as possible in the mission. The primary work of the U&amp;ST culminated in the development of a User Requirements Document (URD) with input from all stakeholder departments and their representatives.
  • RSAT-2 has benefitted from RSAT-1 market knowledge. Attention paid to provide market-driven improvements while keeping operations costs to a minimum. Flexibility to adapt to changing market needs is also important. For large volume users, the new distributed ordering system will enable them to place and track their orders from acquisition to production, and delivery. Made possible using web technology.
