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 1250,000
  (WFI) to 150,000 (CCD)
• University of São Paulo Geological studies
• Agricultural Agency (EMBRAPA) Monitoring the
  expansion of agricultural area

16
CBERS-Associated Software Technology
17
RD 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

Segmentation and Classification
19
Restoration

• Objective
• Correct sensor distortions
• Reduces the blur effect

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

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!
