13. 13 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

14. 14 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)

15. 15 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

31. 31 Perspectives for CBERS-2 and CBERS-3/4

32. 32 Perspectives for CBERS-2 Estalishment of a Joint Cooperation Agreement for Ground and Application Segments Strong partnership between CRESDA and INPE

33. 33 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

34. 34 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

35. 35 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

36. 36 Concluding Remarks: The Rôle of CBERS for International Cooperation

37. 37 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”

38. 38 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!

39. 39 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!
