8 !Prof. Wang Qinmin $ Director of SIRC $ Chief of the Science and Technology Agency, Fujian Province Chinese principal of the project: agriculture application in Fujian

9 $ Got his doctoral degree in $ Engage in the Geo-information science, remote sensing technical application and research, industrialization popularizing $ Devote to the Tenth Five Year planning in remote sensing and ocean monitor field of Ministry of Science and Technology $ dedicate himself to organization and research with the international collaborative projects $ Advocate, plan and organize the project of " Digital Fujian "

10 Main Projects: $ The Tenth Five Year country 863 information field project: Demonstration for trade 3S use and service. $ the State Ministry of Science and Technology project: the South cloudy area forest resource remote sensing monitor technological development. $ Digital Fujian 131 core key project -Fujian Province government information sharing platform with the information resources to develop. $ Collaborative project between China and Japan: Chinese environmental remote sensing and GIS joint study. $ the scientific and technological great project in Fujian Province -the marine function zoning information management system of Fujian Province. $ the scientific and technological great project in Fujian Province - forestry of the radar satellite data, agriculture monitors and demonstrates

11 Test site describtion E N the annual average temperature is 21 The area is 12897km 2, 77% is below the height of 500m. Main land use type: $ arable land (12.91%) $ garden plot(13.45%) $ forest(52.49%) Zhang Zhou

12 Main agriculture land use types! Crops (rice, sweet potato, potato, sugarcane... )! Vegetable garden! Orchard (bananas, litchi, longan, orange and grapefruit... )

13 Rice Growth season of all crop types spreads all year round, from spring to winter. The rice growth calendar is approximately from April to October

14 Bananas In Zhangzhou, banana is planted extensively and is provided all the year, and reached its production climax during June or July

15 Litchi and longan The trees are Evergreen, bloom in spring, ripe in summer/autumn. Litchi and longan are similar in growth and fruiting habit

16 Orange and grapefruit

17 narcissus the growing period of Narcissus is about 3 years, it grows best during December, After that the leaves begin to turn yellow and wither

18 Ground data! Field survey is no problem during ! Rice phenological stages may be collected.! As for the collection the rice yield for sampled fields, we have to contact with local government. So it s impossible to decide whether we could collect the data now. But the historical total area and yield for main crop of every county will be collected

19 Some extended studies(1)! Xiamen local government pays much attention to this cooperation, and hopes some relevant units in Xiamen may participate in our project.! Relevant units: " Information Center of Xiamen Environmental Protection Bureau " Key Laboratory of Marine Environmental Science, Xiamen University " Third Institute of Oceanography, SOA (State Oceanic Administration) experience in ocean color remote sensing

20 Some extended studies (content)! Coastal water quality (like suspended sediment, chlorophyll ) with ocean color sensor MERIS! Sea surface temperature (AATSR)! Shallow water bathymetry with SAR/ASAR

21 Relevant studies! ERS SAR & Jers-1 SAR processing " Ortho-rectification " Speckle noise suppression " Data fusion for SAR and TM! Relevant studies in Zhangzhou district

22 Ortho-rectification rectification ERS SAR Jers-1 SAR

23 Speckle noise suppression (different algorithms) Media Mean Original Frost Local-region Lee-Sigma Gamma-MAP Lee

24 Speckle noise suppression (different filtering window size) original

25 Data fusion of SAR and TM (different decomposed level for the fusion algorithm based on wavelet transform) TM 1 4 SAR

26 Data fusion of SAR and TM (different fusion algorithm) TM SAR Biorthogonal wavelet Orthogonal wavelet Brovey PCA IHS multiplication

27 TM Typical agriculture zone Typical agriculture zone % Bananas: along river % Orange & grapefruit: ChangTai, NanJing, PingHe % Litchi & longan:zhangpu, YunXiao, Zhao an % Flowers: near Zhangzhou city, along road

28 Forest remote sensing monitoring in Zhangpu County TM and SPOT5 TM Fused imgae
