  9. 9. 9 Copernicus Global Land Service
  10. 10. 10 Copernicus Global Land Service
  11. 11. Crop monitoring information support •Qualitative analysis -Highlight areas with anomalies -Reduce the field of investigation of the ground truth. -Convergence of evidence with different sources of information (RS and field network) •Quantitative analysis - Yield forecast •Impact analysis -Quantify the extension of an anomaly -Area, villages, population, production
  12. 12. Demonstration of the use of Copernicus product •Generate standard crop monitoring analysis products from Copernicus Land service data. •Preliminary test made with fAPAR monthly composite •Over Slovenia •Using the JRC free software SPIRITS
  13. 13. Post-Processing Software: SPIRITS •JRC-VITO development: Software for the Processing and Interpretation of Remotely Sensed Image Time Series •All tools to exploit RS time series & to make agro- meteorological bulletins •Freely available, incl. Manual & Tutorials •Many users: VITO, JRC, FAO, WFP, Africa •Training sessions (± 50 so far)
  14. 14. The challenge of information analysis The analysis support products •MAP analysis over Slovenia - fAPAR evolution and anomalies - Return frequency of fAPAR anomalies - Cluster analysis •GRAPH analysis per admin/land use - fAPAR profil evolution - at admin level 1 and 2 - over agriculture or forest/natural zones
  15. 15. The challenge of information analysis The reference data set •Analysis made at statistics region and districts •Through GLC2006 agriculture area
  16. 16. MAPs analysis protocols in SLOVENIA fAPAR 1 dekad at a time N dekads at a time ANOMALIES Cluster VALUE Cluster Relative difference Return frequency
  17. 17. Ten day fAPAR Visualize the vegetation development extension Need to display all the time series to get the time evolution 10 day fAPAR data
  18. 18. Ten day fAPAR anomalies Visualize the vegetation development anomalies (stress, drought) Difficult to identify area with persistent anomalies
  19. 19. Ten day fAPAR anomalies Introduce another way to measure the anomalies Use return frequency value
  20. 20. Cluster analysis of fAPAR evolution over AGRICULTURE space and time synthesis combine start/duration/intensity/extension of fAPAR values focus on land use (here “agriculture”) - Low fAPAR + 1 2 3 4 5 high fAPAR
  21. 21. Cluster analysis of fAPAR anomalies space and time synthesis combine start/duration/intensity/extension of an anomaly along the season focus on land use (here “agriculture”) Mean 1999-2012 2013 above + 1 2 3 4 5 - 2013 below Class with a significant negative anomaly: -20% below mean during more than one month

  23. 23. fAPAR profil evolution  per statistics region and per land use (agriculture)
  24. 24. fAPAR profil evolution  per district and per land use (agriculture)
  25. 25. NDVI profil evolution  to analyse late/early start and higer/lower vegetation  by comparing 2013 with average/min/max GOOD DEVELOPMENT BELOW AVERAGE PASTURE AGRICULTURE
  26. 26. Seasonal fAPAR evolution over the all historical series  under implementation  per statistics region and per land use (agriculture)  comparison of on going season with all the historical years  identify late start, shortened season, lower/higher potential
  27. 27. Seasonal fAPAR anomalies IMPACT evolution  under implementation  per statistics region and per land use (agriculture)  calculate the agriculture areas affected by different anomalies classes along the season (here compared to mean) For ONE date (ex. 20130911) For the season (ex.20130501 to 20130911) km2
  28. 28. Conclusion •Copernicus Global Land service is operational –Since 2013 … EC budget available till at least 2020 –Sustainable ‘daily’ delivery of NRT global products at ‘1km’ •13 global bio-geophysical variables •Linked to consistent time series •Continuous quality monitoring •Continuous evolution –In cooperation with FP7/H2020 projects –Introduce back-up sensor •Based METOP-AVHRR (sustain deliveries) –Increase Spatial resolution 1km -> 300m •2014: vegetation variables over Europe •2015: more variables over Globe –Exploit new capabilities from sensors •2015 (tbc) SWI@1km: Metop ASCAT + Sentinel-1 •2016(tbc): add Sentinel-3 (1km / 300m), +PROBA-V -> S3A+B •(tbc): Daily Global at 100m –Add new products •E.g. Phenology, Snow, Water Level, Vegetation Counter, …. –Add hot-spot monitoring •Sentinel-2 based, e.g. 30m FAPAR
