With ESA Coastal Erosion Evolution, our ambition is to reaffirm that the coastal erosion issue from space has to be tackled in close connection with the coastal community and stakeholder requirements, in order to align the satellite products with coastal areas particularities and the end user needs. But in the meanwhile, the satellite products cannot be site-specific and previous activities have shown a couple of satellite-based products (shoreline extracted from Sentinel-2 time series, nearshore bathymetry and sediment stocks) as having the best potential for providing huge benefits at both local and large-scale for the assessment of coastal change. Emphasis should be put on during the follow-on activities this year.
Concurrently the ESA Coastal Erosion project, the opportunity was taken to start the diversification of coastal erosion products by considering the issue in tropical coastal regions. Indeed, i-Sea has been awarded the Challenge Copernicus in French Guyana by CNES in response to the regional coastal observatory (Observatoire de la Dynamique Côtière) stakeholders to have an operational satellite-based solution for the monitoring of coastal dynamics in french Guyana. With the extension of ESA Coastal Erosion activities, the Space for Shore portfolio is once again likely to be enriched with new coastal erosion products typical of glacial environments.
