MERIS captures all of Europe from orbit

07.02.2005


See the face of Europe from space – with the entire continent covered in consistent detail. This set of true-colour Envisat satellite mosaics depicts the ten newest members of the European Union as well as ESA’s 15 current member states and two pending accessions of Greece and Luxembourg.



The crowning mosaic in the series represents approximately 1.6 million square kilometres of European territory at 300-metre resolution. All the mosaics were produced using the Medium Resolution Imaging Spectrometer (MERIS) instrument on ESA’s Envisat environmental satellite, working in full resolution mode. The Innsbruck-based company GeoVille produced the mosaics for ESA. They are made up of around 160 separate MERIS images.

"Most of the images are taken in the time period between May to August 2003, and we started to order images around December of that year," explains Frederic Petrini of Geoville. "We finished the first part of the project eight months later, and it took us another two months to finish the all-Europe mosaic."


Once the images are ordered they were georeferenced, then mosaicked together. A colour match is run and irregularities such as clouds had to be corrected for. Millions of clouds were masked and substituted with actual data.

The mosaic scale is constant, so it needs more than six images to cover the whole of Germany while small countries like Luxembourg can be covered by only one image.

"I envisage that MERIS mosaics like this one will in future be produced more frequently to identify changes happening on our planet," adds GeoVille’s Christian Hoffman. "It is an excellent sensor to make the link between higher resolution data used for hotspot monitoring and coarser resolution data used so far for global monitoring."

The Europe mosaic can also be browsed at full resolution using the ESRIN Web Map Server at the link on the right navigation bar.

Im Focus: A quantum walk of photons

Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.

Im Focus: Turmoil in sluggish electrons’ existence

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...

Im Focus: Using graphene to create quantum bits

In the race to produce a quantum computer, a number of projects are seeking a way to create quantum bits -- or qubits -- that are stable, meaning they are not much affected by changes in their environment. This normally needs highly nonlinear non-dissipative elements capable of functioning at very low temperatures.

In pursuit of this goal, researchers at EPFL's Laboratory of Photonics and Quantum Measurements LPQM (STI/SB), have investigated a nonlinear graphene-based...
