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 Data Reception Image Production Software Develop. Applications

5 CCD image of Brasilia

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

7 São Paulo Coast (CCD)

8 IRMSS: Brazilian Coast (NE)

9 São Paulo – Rio Janeiro (WFI)

11 WFI: Belo Horizonte Mining = dark regions

12 WFI Mosaic: São Paulo State

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 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 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

16 CBERS-Associated Software Technology

17 R&D in Image Processing and GIS SPRING – Image processing and GIS software. Multi-platform (Windows, Linux, Solaris) Web: ( downloads)

18 Segmentation and Classification

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

20 Restoration Filter

21 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

22 Registration System Interface

23 Combination of CBERS Images

24 CBERS Application Examples

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

26 Segmentation Over Color Composite

27 COLOR COMPOSITIONFINAL MAP Classification DEFORESTATION PRIMARY FOREST WATER BODIES NON-FOREST

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

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

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 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 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 Concluding Remarks: The Rôle of CBERS for International Cooperation

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 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 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!
