The possibility to count the accesses to a site and monitor the internal movements of people can be useful in many different scenarios. In this respect, a WiFi network can be exploited to count accesses and estimate users position. This study extends this principle to a wide spatial area and to a large number of users, introducing synergies between Big Data and localization techniques. The 2016 Open...
The discovery of anomalies and, more in general, of events of interest at sea is one of the main challenges of Maritime Situational Awareness. This paper introduces an event-based methodology for knowledge discovery without querying directly a large volume of raw data. The proposed architecture analyses the maritime traffic data to detect maritime traffic patterns and events and aggregate them in...
The possibility of detecting and tracking oil spills by satellite remote sensing means has been illustrated from theoretical and technical points of view. In the beginning, optical remote sensing on oil spill detection was introduced. Oil and its characteristic spectral signature can be detected using optical sensors on onboard satellites. The larger part of the chapter is devoted to remote sensing...
In this paper the potential of COSMO-SkyMed is examined for oil spill detection, focusing on the Adriatic Sea. The low revisit time and the radiometric characteristics of COSMO-SkyMed point to good suitability of the instrument for operational oil spill detection in the area. The possibility of querying Automatic Identification System (AIS) data over the area, with almost no coverage gaps, offers...
