OLF products are organized in product families.
The attention is focussed on the identification and
production of indicators of the temporal behaviour of the growing season, and
the inter-annual and inter-seasonal comparison. Input data include 10-day
observations of NDVI, fractional cover, surface temperature and similar
indicators at 1km ground resolution. OLF process will generate information on
the phenology, i. e. standardized indicators
of start, maximum and end of the growing season, and differences (change detection)
with reference datasets. Output data will include 10-day delivery of
environmental indicators at full as well as at reduced resolution (typically
1°*1°). The system is conceived to be able to generate both real time
(every 10-day) and post season products.
Deliverables will be both the tools to generate the above
mentioned products and the data generated for the period 2000-20003.
In this work package UCL provides the scientific &
technical input and JRC/GVM is responsible for algorithm implementation
- Multispectral change analysis
A set of change detection methods are being tested and
will be put in place to assess environmental status from seasonal multispectral syntheses to identify areas of possible
vegetation degradation and land cover change. The output is typically a
seasonal map depicting spectral disturbances, to be further qualified as
environmental degradation with external validation The exploitation of both
low (1km) and medium resolution (250-300 m)satellite data are being evaluated,
according to availability, to identify changes in the spatial extension of
two key land-cover categories: forest and the agricultural domain. This
specific action is carried out on sub-continental windows of interest.
Deliverables will be both the tools to generate the above
mentioned products and the data generated for the period 2000-20003.
In this work package RSS GmbH provides the scientific
& technical input and JRC/GVM is responsible for algorithm implementation.
- Fire disturbance analysis
Automated analysis of seasonal patterns of fire and burned
surfaces are developed, as well as inter-seasonal comparison procedures. A
particular attention is given to fire & burned surface data
recalibration. It is indeed noteworthy that the identification capacity of
available low-resolution space sensors to active fires and burned surfaces is
very much governed by the specific conditions of the ecological unit under
analysis.
Deliverables will be both the tools to generate the above
mentioned products and the data generated for the period 2000-20003.
In this work package IICT provides the scientific input
and JRC/GVM is responsible for algorithm implementation.
- Seasonal
water resource analysis
The attention is focussed exclusively here on the semi
arid regions of Africa. The application is built on
the consolidation of an existing and tested methodology and aims at providing
indication of surface water availability (seasonal component: start or
replenishment, completion of drainage / evaporation) in temporary water
bodies.
Deliverables will be both the tools to generate the above
mentioned products and the data generated for the period 2000-20003.
In this work package JRC/IES provides both the scientific
input and algorithm implementation.
- Assessment on environmental status /
Africa and Boreal Eurasia
These two geographically-tuned components are similar in
substance. The objective is to combine; using GIS tools, the parameters
delivered by the previously described work packages, as well ancillary
environmental information such as rainfall, air temperature, etc… and
socio-economic information if available and relevant and to identify areas
with anomalous properties based on convergence of evidence technique. The
output can be generated by user-defined key ecosystem categories and areas,
such as: boreal forests, tundra, tropical forests, woodlands, rangelands,
relevant biodiversity sites, protected areas with special legal status, etc….
The output is typically information on land cover status useful to determine
the state of the vegetation and potential for land cover conversion. This
information is meant to be ready for use in reports and bulletins aimed at
end users with a typical “decision making” profile.
The deliverable is a tool that permits user-defined
analysis.
In these work packages CNR/IREA and CEH provide the
scientific input for Africa and Boreal Eurasia
respectively, and JRC/GVM is responsible for algorithm implementation.
Availability of
deliverables
At the end of the project it is expected that the various
products generated for the 2000-2003 period will be made available for the
broader public.
Standard pre-processing methods are being developed and coded
in such a way that they can be integrated in operational EO data processing
facilities.
User oriented data analysis tools are meant to be made
available to the user community.
Access to results is subject to copyright rules laid down
in the consortium agreement signed by all GEOLAND partners.
