1. A Proposal for a Global Forest Information System Gilberto Câmara, INPE Lúbia Vinhas, INPE Dalton Valeriano, INPE Fred Fonseca, Penn State Univ. Clodoveu Davis, Univ Minas Gerais - Brazil

2. How can Brazil achieve its deforestation targets? Brazilian National Plan for Climate Change

3. Degradation and deforestation T2 – Partial Loss of forest structureT1 - Selective logging T3 – Collapse of forest structure Barlow and Peres (2008) T4 – Clear-cut area

4. T1,5 – Loss of undercover due to fire Progressive degradation T1 – Selective logging T2 – Partial loss of forest structureT3 – Complete loss of forest structure

5. Severely degraded forest Pasture Marcelândia (MT, Brazil) – Jan-2008 (4.000 ha) Pasture inside a forest area Progressive degradation: the final steps

6. ~230 scenes Landsat/year Yearly detailed estimates of clear-cut areas PRODES: Clear-cut deforestation mapping

7. 15-day alerts of newly deforested large areas DETER: Real-time deforestation monitoring

8. DEGRAD: Forest degradation Forest degradation in LANDSAT image (June 2008)

9. 166-112 116-113 116-112 TerraAmazon – open source software for large-scale land change monitoring Spatial database (PostgreSQL with vectors and images) 2004-2008 data: 3 million polygons, 300 GB images, 250 GB vector data

10. Alerta DETER nov-2007 Landsat/TM (August 2007) MODIS (November 2007) How hard is to use MODIS? Detection of deforestation and degradation in MODIS requires much expertise (low-resolution artifacts)

11. Clearing area for pasture Checking DETER´s data (February 2008) Validation is essential for credibility!

12. How hard is to use ALOS? ALOS L-HH image (July 2007) ALOS L-HH image (November 2007) LANDSAT TM image (June 2007) The real thing (Marcelandia, Brazil) Backscatter is seasonally variable (chance of false positives and false negatives)

13. In search of the pure pixels (the Holy Grail of remote sensing) Methods: Mixture Model Original LANDSAT TM image Soil component Shade component Vegetation component

14. Soil component Segmented soil component Methods: Segmentation

15. Deforestation 2005-2006 Deforestation 2004-2005 Forest Previous deforestation Methods: Classification

16. A lot of work goes into editing and auditing! Methods: Editing and auditing

17. Results: Wall-to-wall maps Deforestation is spatially autocorrelated (wall-to-wall maps are required)

19. The Anti-Uncle Scrooge Principle A pixel unused is a penny wasted LANDSAT data archive (USGS) A penny saved is a penny earned Value comes from use!

20. What is a public good? Non-rival...[goods] which all enjoy in common in the sense that each individual's consumption of such a good leads to no subtractions from any other individual's consumption of that good... (Samuelson) Non-excludable it is impossible to exclude any individuals from consuming the good

21. Almost all spatial data are public goods

22. Global Forest Information System The Digital Earth vision … images, maps, research results, laws, policies, and citizen-provided information can be indexed, searched, discovered and used by any interested parties...

23. A Global Forest Information System LANDSAT TM (30 m) CBERS HRC (2,5 m) Navigate, describe, understand: image navigation and processing, production and dissemination of information, knowledge-building using semantics

24. “A few satellites can cover the entire globe, but there needs to be a system in place to ensure their images are readily available to everyone who needs them. Brazil has set an important precedent by making its Earth-observation data available, and the rest of the world should follow suit.”

25. Data for the world´s tropical areas Global satellite data in 5 meter+ will be free Concerted action needed with benefits to all involved Cuiabá Boa Vista Chetumal Maspalomas Aswan Jo´burg Nairobi(?) Accra(?) Urumchi Miyun Ghuangzhou Darwin)
