The CIVIS Summer School, to be held from 28 June to 9 July 2021, aims at providing advanced training to young European environmental and Earth scientists about the latest geospatial methods applicable to environmental sciences, geography and urbanism, focusing on applications of the Copernicus satellites.
On this occasion, RUS Copernicus will hold a remote hands-on training session to show the use of Sentinel-1 products for urban applications.
As the world is facing a large increase in population, reliable information on urban areas is required to assist and help in the decision-making process. Different methods are available to gather this information, but Earth observation imagery offers a suitable approach based on the coverage and type of data provided. Optical products, such as Sentinel-2 or Landsat are ideal for urban monitoring, but are limited by cloud cover. SAR sensors such as Sentinel-1 are not affected by cloud cover and can therefore be used to overcome this limitation. However, they require significantly different processing than optical data.
During this session, we will use the RUS Copernicus Virtual Machines to process a multi-temporal dataset of Sentinel-1 SLC products with the SNAP software and to derive coherence in order to delineate the built-up areas, as the latter usually exhibit high coherence values compared to vegetation and other natural surfaces. We will then map urban areas over a region of interest in Germany with different methods using Python scripts provided in JupyterLab and we will compare their results.
This event is a closed training session. More information is available on the event Web page.
