  1. Wang Yanyan Beijing Municipal Bureau of Statistics October 2008 Applying Remote Sensing Technology to Agricultural Statistics of Beijing

  2. Contents Introduction About the projects Achievements Current progress of the practical application

  3. Introduction Brief Review of Remote Sensing (RS )Application in China Researches and practices have been conducted by governmental departments and research institutes since 1980’s. Statistical departments began to use RS in recent years: National Bureau of Statistics of China

  4. Introduction Why we use RS - advantages of RS compared with theconventional methods • Spatiality : spatial distribution • Objectivity: avoid subjective factors or artificial interference • Efficiency : up-to-date data, less time, money, labor force spent on statistical survey

  5. Introduction What we do on RS 2 projects based on RS: Construction of Statistical Visual Platform based on “Beijing -1 Microsatellite” Beijing Statistical Ecological Resource Remote Sensing Measurement Operation System

  6. About the Projects Targets of our projects • Study the methodology and techniques fit for RS application to Beijing agriculture • Develop a software platform • Achieve the RS vocational operation in agricultural statistics of Beijing

  7. Subjects of the Projects Area measurement of wheat and maize Yield estimation of wheat and maize Area measurement of agricultural facilities Vegetation coverage monitoring and NPP (Net Primary Production) estimation Development of System Software About the Projects

  8. About the Projects Main methods of the projects • Precise Extraction Method Based on “Parcel of Field” Unit • Parcel-Level Method of RS Integrated with Spatial Sampling

  9. About the Projects The methodology and techniques system contains: • Key Methodology and Techniques • Implementation Plan • Accuracy Evaluation System • Emergency Program

  10. Spatial distributions of wheat and maize area Spatial distributions of agricultural facilities area System software demonstration Achievements

  11. Wheat planting area in Beijing 2007

  12. Maize planting area in Beijing 2007

  13. Agricultural facility area in Beijing 2007

  14. System Software The system software includes 7 sub-systems: • Operation Management System • Ecological Resource Measurement System • PDA Field Survey System • Product Fabrication System • DataRelease System • Database Management System

  15. Log-in Interface of Ecological Resource Measurement System Ecological Resource Measurement System subjects Log in

  16. Ecological Resource Measurement System

  17. DataRelease System Beijing Ecological Resources Data Publishing System Based on RS Seasonal vegetation coverage Agricultural facility area NPP Crop area Crop yield

  18. DataRelease System Beijing Ecological Resources Data Publishing System Based on RS Menu Spatial location Attributes inquiry Data presentation Data analysis

  19. Current progress of the practical application • Multiple data sources; • Scientific methods; • Desirable accuracy; • Timely submission; • Simple procedure and manageable software; • Emergency program.

  20. Current progress of the practical application • Provided with all these mentioned above, some of the subjects are now basically ready for vocational operation. • And this RS system for agricultural statistics of Beijing is planed to be actually used in 2009.
