Our offers and solutions

With our team of scientists and experts, we are able to offer and find solutions, analyse the data collected by Earth Observation satellites and provide users with reliable and usable products.


Earth Observation data from space are essential to understand our planet, current and future environmental challenges. Data collected by satellites help us monitor everything from rising sea level to snow cover or water quality. Every day, satellites collect huge amounts of data about the Earth. These data are raw and require a series of processing steps to make them usable.

The Earth Observation unit works every day with these data. We design algorithms and develop software so we are able to operate services and deliver user products.
