Global Land Service

• Support and consolidate:

– EU contribution to GEO/GEOSS

– EU policies at international level

• e. g. Climate and Development policies

– EU commitments under international treaties and conventions

• e. g. UN “Rio” conventions: UNFCCC, UNCCD, UNCBD

• EU Policy focus:

– Crop Monitoring and Food security in/outside Europe

– Biodiversity, Protected areas and Forest cover monitoring

– Drought Assessment and Desertification

– Carbon modeling, land use and land cover change

– Support to Earth Observation African Activities

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

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

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)

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

The challenge of information analysis The reference data set

• Analysis made at statistics region and districts

• Through GLC2006 agriculture area

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

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

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
