In real-time and high-resolution Earth observation imagery, Low Orbit (LEO) satellites capture images that are subsequently transmitted to ground create an updated map of area interest. Such maps provide valuable information for meteorology or environmental monitoring, but can also be employed in near-real time operation disaster detection, identification, management. However, the amount data g...
The Doctorate of Geomatics and Infrastructures continues the tradition of the previous Doctorate in Geodesy and Geomatics, dating back to the first cycle of doctorates in Italy of the years 1983-86. Thus, according to the vision of the Doctorate School of Politecnico di Milano, we are working now within an interdisciplinary environment. The original field of geomatics, which in any way was alre...
Thanks to recent progress in satellite-based remote sensing technologies and object oriented image analysis, as well as to the availability of new very high-resolution sensors, it is now possible to design gas pipeline monitoring systems, as has been demonstrated by the co-funded European “PRESENSE Pipeline REmote SENsing for Safety and the Environment” project. In parallel, the European Space ...
Terrestrial gamma-ray flashes (TGFs) are very short bursts of high-energy photons and electrons originating in Earth's atmosphere. We present here a localization study of TGFs carried out at gamma-ray energies above 20 MeV based on an innovative event selection method. We use the AGILE satellite Silicon Tracker data that for the first time have been correlated with TGFs detected by the AGILE Mi...
Small satellites have limited payload and their attitudes are sometimes difficult to determine from the limited onboard sensors alone. Wrong attitudes lead to inaccurate map projections and measurements that require post-processing correction. In this study, we propose an automated and robust scheme that derives the satellite attitude from its observation images and known satellite position by ...
With the development of modern remote sensing technology, a variety of earth observation satellites could continue to tremendously provide image data of different spatial resolution, time resolution, spectral resolution remote sensing, and the remote sensing data obtained is increasing with great capacity, which forms multi-source image pyramid in the same area. To play the advantages of a vari...
