The process of searching and analyzing data in order to discover potentially useful information is a crucial matter when dealing with large databases. Considering the huge amount of data collected by satellite observation systems, opportunities to generate multispectral image time-series are increasing. Exploratory methods are needed to understand the dynamics of Earth observation scenes and of...

A satellite, in its orbit, is affected by perturbing forces, such as atmospheric drag, solar radiation pressure, Earth oblateness, and gravity of the celestial masses (other than the Earth). In this paper, the effects of these forces on the trajectories of different types of LEO satellites and a sample satellite (Z-SAT) are discussed. A few analyses are done on these orbits and the relevant res...

Involved in disaster management support for more than 10 years, SERTIT’s Rapid Mapping Service is specialized in the rapid delivery of crisis information derived from Earth Observation satellite imagery, in particular within the framework of the International Charter “Space and Major Disasters” or European and National emergency programs. This service, available 24/7/365, provides in a rush mod...

The Global Earth Observation System of Systems (GEOSS) is structured into nine societal benefit areas, which all will require information related to the forest cover. Utilisation of methods that combine satellite remote sensing and in-situ observations are the focus of GEOSS. The best way to feed forest information into GEOSS is most likely from the national level. In Sweden and Finland, nation...

For global monitoring, satellite remote sensing is a useful tool to cover wide area of earth surface for large scale observation. However, the correct interpretation of satellite images remains a challenging problem and the retrieval of earth related information from the processing and analysis of the satellite data requires the development of suitable artificial intelligence based technique. I...

Quantifying and monitoring the spatial and temporal dynamics of the global land cover is critical for better understanding many of the Earth's land surface processes. However, the lack of regularly updated, continental-scale, and high spatial resolution (30 m) land cover data limit our ability to better understand the spatial extent and the temporal dynamics of land surface changes. Despite the...
