This webinar session is organized by RUS Copernicus in support of the GEOBIA Summer School 2020 held by the Department of Geoinformatics (Z_GIS) of the University of Salzburg and UNIGIS, with support of CopHub.AC and the European Space Agency (ESA).
The first part of the webinar will be dedicated to the basics of Sentinel-3 Ocean and Land Colour Instrument (OLCI) image processing for large scale vegetation monitoring. In the second part, we will focus on mapping burned areas, using the Sentinel-2 MultiSpectral Instrument. You will learn how to access, process, analyse and visualise the free data acquired by the Copernicus satellites and employ the ESA SNAP Sentinel Toolbox.
Land Monitoring with Sentinel-3
Land surface dynamics represents one of the key driver to assess environmental change at different scales. Monitoring activities is relevant to detect and understand those patterns and to measure the ecosystems resilience.
Satellite based Earth observation methods are one of the best approaches to perform those tasks at local, regional, and global scale. The Sentinel-3 OLCI provides continuous observations with high temporal frequency ensuring the capability to monitor vegetation dynamics on various scales.
Burned Area Mapping with Sentinel-2
Accurate and rapid mapping of areas damaged by fire is fundamental to support fire management, account for environmental loss, define planning strategies and monitor the restoration of vegetation. In recent years, increase in wildfires was observed globally, triggered by adverse weather conditions and human activity or combination of both.
Optical remote sensing provides accurate and rapid information about burned areas, often using various vegetation indexes and specific band ratios such as the Normalized Burn Ratio (NBR). With 10m spatial resolution, high temporal frequency and free and open access to all acquisitions, Sentinel-2 MSI is an ideal tool to map and monitor wildfire vegetation damage and recovery.
