As a large part of the gross domestic product is derived from coastal activities, coastal areas are economically important for many countries. That is why coastal erosion is a major problem for many parts of the world. For example, along the northwest coast of Africa, average rates of coastal retreat have been measured and reach between one and two meters per year.
Whether the cause is due to natural or human activities, it has important effects on the populations who can no longer live close to the coastline and the infrastructure. As climate is changing, salinization of water and soils, degradation of ecosystems and flooding due to sea level rise are also some of the few significant problems we will have to deal with. Monitoring of coastal environments and tracking their evolution is thus essential to provide information to policy and decision-makers on local, regional and national levels.
Remote sensing and satellite imagery are widely used for environmental monitoring of the Earth’s surface and thanks to the Sentinel-1 mission, an innovative approach can be explored to follow the evolution of shorelines.
In this webinar, we will download and process Sentinel-1 Ground Range Detected (GRD) products to monitor coastal changes due to erosion in West Africa. We will also show you how to benefit from the RUS Service, to download, process, analyse and visualise the open data acquired every day by the Copernicus satellites.
