  1. CBERS: the Brazilian Experience Gilberto Camara Director for Earth Observation INPE Workshop – 3 Years of CBERS, Beijing, October 2002

  2. Overview • CBERS Ground and Application Segment in Brazil • CBERS Products and Distribution Statistics • CBERS Associated Software Technology • CBERS Applications • Perspectives for CBERS-2 and CBERS-3/4 • The rôle of CBERS as an International Cooperation program

  3. CBERS Ground and Application Segment

  4. CBERS Ground and Application Segment Data Reception Image Production Software Develop. Applications

  5. CCD image of Brasilia

  6. CCD: Agricultural Region in São Paulo Crops= soy (red) and harvest (green)

  7. São Paulo Coast (CCD)

  8. IRMSS: Brazilian Coast (NE)

  9. São Paulo – Rio Janeiro (WFI)

  10. WFI: Belo Horizonte Mining = dark regions

  11. WFI Mosaic: São Paulo State

  12. CBERS-1 Image Production • Total number • 2000 = 653 products • 2001 = 757 products • 2002 = 863 products (September) • One product = CCD scene (+IRMSS) • CBERS demand is similar to LANDSAT

  13. Promoting CBERS • Partnerships • Universities, research institutes and industry • Education projects • High-school teachers • ISPRS – International society for remote sensing • Workshops/symposium (SBSR, SELPER, IRSE, etc)

  14. CBERS: Partnership examples • University of Michigan: mapping selective logging of timber (wood) in Amazon • University of Viçosa (Brazil): Vegetation index mapping • Military: maps with scales ranging from 1:250,000 (WFI) to 1:50,000 (CCD) • University of São Paulo: Geological studies • Agricultural Agency (EMBRAPA): Monitoring the expansion of agricultural area

  15. CBERS-Associated Software Technology

  16. R&D in Image Processing and GIS • SPRING – Image processing and GIS software. • Multi-platform (Windows, Linux, Solaris) • Web: http://www.dpi.inpe.br/spring (25.000 downloads)

  17. Segmentation and Classification

  18. Restoration Corrected image Digital image Restoration filter scene sensor 1 1 f (cycles/pixels) f (cycles/pixels) • Objective • Correct sensor distortions • Reduces the blur effect

  19. Restoration Filter

  20. Image Registration and Mosaicking tools • Objective • Combine two images to generate a large-area composite • Amount of data is very large • Difficult to get control points manually • INPE developed a semi-automatic registration system

  21. Registration System Interface

  22. Combination of CBERS Images

  23. CBERS Application Examples

  24. A comparison study between CBERS IR-MSS and Landsat TM images to evaluate deforestation in the Brazilian Amazon

  25. Segmentation Over Color Composite

  26. DEFORESTATION PRIMARY FOREST NON-FOREST WATER BODIES Classification COLOR COMPOSITION FINAL MAP

  27. Comparison of Area Estimation

  28. CBERS images in Remote Sensing Training Course for Grade Teachers

  29. Perspectives for CBERS-2 and CBERS-3/4

  30. Perspectives for CBERS-2 • Estalishment of a Joint Cooperation Agreement for Ground and Application Segments • Strong partnership between CRESDA and INPE

  31. CRESDA-INPE Cooperation • Standards for CBERS image products; • Quality control and quality assessment plans for CBERS images; • A joint commercialization proposal for the marketing of CBERS images for countries other than Brazil and China

  32. CRESDA-INPE Cooperation • Joint image reception and image production ground station for the CBERS 3 and CBERS 4 satellites • Image processing software to extract information from CBERS • Establishment of an applications development center to develop end-user products

  33. Ground Segment: CBERS-3/4 • To be developed as part of the joint agreement between Brazil and China • Establish an international network of receiving stations for CBERS-3/4 • INPE Initiatives • Initial development of ground station for CBERS-2 • Replace CBERS-1 processing station

  34. Concluding Remarks: The Rôle of CBERS for International Cooperation

  35. Significant Contribution of CBERS • Competitive advantages of RS imagery • When there is a need to routinely monitor a large area consistently, reliably and/or independently. • Where there is a need to gather information rapidly about events whose location and timing are unpredictable. • Where there is a need for cost-effective cartographic mapping, and imagery can replace or complement aerial surveys. • CBERS serves the “public good”

  36. Significant Contribution of CBERS • International Earth Observation satellites • USA and Europe: Earth Observation as commercial service • Increase image cost for other countries • China and Brazil response • CBERS as a “public-good” satellite • International cooperation programs • Major oportunity for CBERS!

  37. Conclusion • Many thanks and honors • CAST for developing CBERS-1 • CNSA and COSTIND for supporting CAST • CRESDA for the application development and cooperation with INPE • May CBERS Project have a long life!
