Natural and man-made disasters have become an issue of growing concern throughout the world. In recent years, the frequency and impact of disasters has rapidly increased across the world due to the higher exposure given by demographic growth and urban expansion. These disasters also have far-reaching implications on sustainable development through social, economic and environmental impact.
The presentation will address the added benefits in using Earth Observation (EO) to monitor and model geohazards from different regions of the world and at different scales when sometimes ground observations are not feasible due to logistic, physical and/or political constraints.
In this framework, we assisted at the exponential growth of EO data gathered by land, sea, air and space-based for environmental studies thanks to the advent of better sensing technologies, improvements in computational resources, easy accessibility to knowledge fostered by the internet and open-source policies and decrease in sensor manufacturing costs.
The ongoing and upcoming amount of EO data being produced will allow for things which would be impossible to be done in the past — but also poses new challenges. This ever increasing rate at which satellite data volume is growing, is in fact overwhelming with more than 100 Tb of data coming from satellites daily. And much, so much more, is yet to come.
Therefore, there is the need of maximizing the value of EO data as the current process of collecting, storing, analysing and distributing this information remains partially fragmented, incomplete or redundant.
The lecture is based on the work and experiences in the Disaster Management Cycle gained from the Earth and Planetary Observation & Monitoring team of the British Geological Survey through different sensors (e.g., Synthetic Aperture Radar, Laser Imaging Detection and Ranging, Optical and multispectral) and platforms (e.g., satellites, aircraft, and Unmanned Aerial Vehicles).
Alessandro is a remote sensing geoscientist at the British Geological Survey with a PhD in Engineering Geology. He is expert in the processing and interpretation of satellite imagery for the detection, assessment and monitoring of natural hazards (mainly landslides) and their consequences over case studies in the UK and overseas countries (e.g., China and Italy). His research activity focuses on the development and usage of space geodetic techniques to detect small movements of the Earth's surface and define the risks implied.
He is working on a wide range of collaborative projects with the University of Nottingham (UK), University of Naples (Italy) and the University at Buffalo (USA). He is an advisor for the Space Generation Advisory Council in Support of the United Nations Programme and a committee member for the British Geophysical Association.
