PROBA-V Preparatory Programme
Duration of the research: December 2010- December 2011
Budget: 1.000.000 EUR
The PROBA-V Preparatory Programme has been set up to prepare the exploitation
of the images from the PROBA-V mission. which was conceived to ensure users
data continuity of VEGETATION-like products.
The current Vegetation instruments onboard the French SPOT 4 and 5 satellites
could only be available until 2013. For almost 15 years now, these instruments
have daily monitored and mapped the worldwide vegetation, thus providing essential
information on crop yields, droughts, desertification, changes in the type
of vegetation, deforestation, etc. to an ever extending user community.
ESA is currently building the Sentinel 3 satellites in view of the European
GMES programme. These
satellites will contribute to the continuation of the availability of Vegetation
type data but will not be operational in due time, thus creating a major time
gap in the data continuity. Moreover, the Sentinel 3 satellites will not meet
some essential requirements of the Vegetation user community.
Therefore, Belgium has decided to build a small satellite mission based on
the successful PROBA
expertise and using state of the art technology. This mission, called
PROBA-V ("V" standing for Vegetation) will redress the data gap
and will fulfil, - even on its own -, all of the specifications of the Vegetation
user community. In that way, it will be a complement to the Sentinel 3 satellites
to be launched after Proba-V.
While the spectral and radiometric characteristics of PROBA-V remain the
same as those of the VEGETATION instruments, the mission will offer improved
SNR, geolocation and spatial resolution. Data products will be made available
at a resolution of 1000 m (VNIR and SWIR), 600 m (SWIR) and 300m (VNIR).
The main objectives of the PROBA-V Preparatory Programme are thus to get
future users acquainted with these new data sets and their full characteristics
and quality, as well as to prepare the full exploitation of Proba-V data sets
with respect to the technical enhancements which are planned.
Spanning a 1-year period, the "PROBA-V Preparatory Programme" is
funded by the Belgian federal government and managed by the Federal Science
Policy Office (BELSPO) and the Proba V International Users Committee
Research projects should concentrate on the evaluation of Proba-V specific
characteristics and use any existing data set as simulation of real Proba-V
They must focus on one of the following areas:
- Assessment of Proba-V mission as a continuity mission to VEGETATION 1
& 2: applied comparison of characteristics as well as combined use of
both data sources for time series studies.
- Impact of enhancements of Proba-V relatively to VEGETATION on the main
uses of VEGETATION data sets. Application areas should concentrate on vegetation
and land cover studies, extraction of biophysical surface parameters...
Improvements due to enhancement of the spatial resolution to 1/3rd km should
be discussed and evaluated.
- Study of applications which were not feasible with the VEGETATION data.
