Digital Earth is a visionary concept for the virtual representation of the Earth that is spatially referenced, interconnected with the world’s digital knowledge archives, and encompassing all its systems and forms, including Earth Sciences and human societies. The project will establish open data and services access, allowing European and worldwide Digital Earth Communities to seamlessly access, produce and share data, information, products and knowledge. This will create a multi-dimensional, multi-temporal, and multi-layer information facility of huge value in addressing global challenges such as biodiversity, climate change, pollution and economic development.


GENESI-DEC (GENESI – Digital Earth Community) will:

  • enlarge the GENESI-DR infrastructures in terms of both resources availability and geographical extent.
  • provide guaranteed, reliable, easy, effective access to a variety of data, facilities, and applications to an ever increasing number of users.
  • enable multidisciplinary collaboration among communities and the creation of user-configured virtual research facilities.
  • integrate new scientific and technological paradigms in operational infrastructures in response to the latest Digital Earth requirements.
  • harmonise operations at selected key infrastructures limiting fragmentation of solutions.
  • assure that the access to data and resources while being homogeneous is secure and controlled (according to provider policies).
  • stimulate, educate and support the creation of virtual research communities.


GENESI-DEC involves key partners of ESFRI projects and collaborates with key actors of Digital Earth and Earth Science initiatives, including the International Society of Digital Earth and GEOSS . Thus efficient use of already existing and planned developments is guaranteed.


Global Monitoring of the Oceans
This image is an example of global composite of MCI (Maximum Chlorophyll Index) for the month of July 2006 where a major bloom event in the southern Baltic can be seen at the upper centre. This index shows the amplitude of a peak near 705 nm in the radiance spectrum of light reflected from the earth%E2%u20AC%u2122s surface, which has been associated with high levels of chlorophyll a in ocean, coastal and lake water targets, such as plankton blooms and floating or benthic plants. Their constant production it is clear that it has a role in monitoring some of the surface, high-chlorophyll events (i.e. %E2%u20AC%u0153red tides%E2%u20AC%9D) and has a role in mapping blooms in ice and floating vegetation %5B more information %5D

The image was obtained assembling more than 400 satellite images from the MERIS sensor aboard the European Space Agency's ENVISAT satellite by using the Grid Processing on-Demand environment (G-POD - http://eogrid.esrin.esa.int).

The Medium Resolution Imaging Spectrometer (MERIS) is a imaging spectrometer that measures the solar radiation reflected by the Earth, at a ground spatial resolution of 300m, with 15 spectral bands in visible and near infra-red and programmable in width and position. MERIS allows global coverage of the Earth every 3 days. The primary mission of MERIS is the measurement of sea color in oceans and coastal areas. Knowledge of sea color can be converted into a measurement of chlorophyll pigment concentration, suspended sediment concentration and aerosol loads over marine areas. It is also used for land and atmospheric monitoring.
