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. 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. 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. 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. The challenge of information analysis The reference data set
•Analysis made at statistics region and districts
•Through GLC2006 agriculture area

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. Ten day fAPAR anomalies
Visualize the vegetation development anomalies (stress, drought)
Difficult to identify area with persistent anomalies

19. Ten day fAPAR anomalies
Introduce another way to measure the anomalies
Use return frequency value

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”)

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. 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)

–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
