3 1. Overview of CRESDA

4 Development of CRESDA Founded in 1991, responsible for operation, management, data processing and distribution, and applications of CBERS satellites.

5 Development of CRESDA In 2005, Chinese government decided to construct the National Land Observation Satellite Ground System based on the CBERS ground system. Now, a band-new satellite data ground processing system has been set up in CRESDA, which can process 5 satellites:hj-1 A/B/C, CBERS-03 & 04 data at the same time

6 Satellites International cooperation CBERS CBERS-01/02 CBERS-02B CBERS-03/04 China land observation satellites HJ-1 ZY-3 HJ-1-A HJ-1-B HJ-1-C ZY-3-01

7 CBERS Satellites CBERS China-Brazil Earth Resources Satellite, which was jointly developed by China and Brazil.

9 CBERS Ground Station Three ground receiving stations for CBERS satellites in Miyun (Beijing), Urumqi and Guangzhou, cover whole land area of China and its surrounding regions

10 HJ-1 Ground Station Three ground receiving stations for HJ satellites in Miyun (Beijing), Kashi and Hainan.

11 Data Distribution Amount of CBERS and HJ Unit: Scenes More than 1 million images distributed in China. 200% annual growth rate of user number since 2005 Over 98% average annual growth rate of data distribution amount Over 90% of the domestic market for mid-resolution products of the same kind of satellites.

13 Typical application Of CBERS Data Disaster Monitoring Agriculture Fire disaster monitoring Mountain fire happened in Dongyong on the Lantao Island in Hong Kong in the evening of November 26, Fire happned on Tuen Mun Mountain in Hong Kong at 4 o clock p.m on November 28. The third level of fire happened on the Pineapple mountain in Tuen Mun in Hong Kong at 2:24 p.m on January 1, The district and area of fire are got through change monitoring by CBERS-02B image.

14 Typical application Of CBERS Data Disaster Monitoring Flood disaster monitoring Agriculture Forestry Cartography Land and Resources Environment Protection Water Conservancy CBERS-02 image on April 8, 2007 ALOS image on July 13, 2007 Great flood of valley happened in Huai River from June to July resident areas had been submerged totally or partly. Although other resident areas were not submerged, they were suffering flood.

15 Typical application Of CBERS Data Disaster Monitoring Agriculture Forestry Cartography Land and Resources Environment Protection Water Conservancy Algal bloom disaster monitoring in Taihu lake China Centre for Resources Satellite Data & Application had monitored algal bloom in Taihu Lake which happened from March to June, 2007 with images of CBERS-02. And the environmental management department gave a high regard. In 2008,CRESDA monitored algal bloom in Taihu Lake again with CBERS-02B image.

16 Typical application Of CBERS Data Disaster Monitoring Agriculture Earthquake monitoring Images before and after earthquake in Beichuan province was contrasted by fusing CBERS-02B HR and CCD image. Damaged houses, roads, bridges and temporary settlements could be recognized clearly.

18 Typical application Of CBERS Data 灾害监测应用 Disaster Monitoring Agriculture Forestry Farm Monitoring Farming is today an economically, socially and environmentally sensitive sector. Satellite imagery now underpins an objective, global and precise approach to resource management and has become crucial to agricultural inventories, crop forecasts, monitoring crop health and soil moisture. infield Cartography Cotton in green frame Land and Resources Environment Protection Distributing infield in AKesu, xinjiang province Water Conservancy Cotton area interpretation in AKesu, xinjiang province

19 Typical application Of CBERS Data 灾害监测应用 Disaster Monitoring Agriculture Tobacco planting area monitoring by CBERS data It is better to recognize tobacco film by fusing CCD and HR panchromatic images of CBERS, and then to monitor the planting area of tobacco.
