Coastal environments are among the most dynamic and vulnerable ecosystems on our planet. In the face of climate change and increasing urbanization, coastal mapping plays a crucial role in monitoring erosion, managing flood risks, preserving marine habitats, and ensuring maritime safety. To address these challenges, accurate and regularly updated bathymetric data is essential.<\/p>\n

Leveraging Earth Observation technologies, satellite-derived bathymetry is revolutionizing underwater data collection by enabling access to remote and difficult-to-survey areas. Our project harnesses the latest advancements in artificial intelligence, particularly deep learning, to enhance depth estimation and improve the accuracy of bathymetric maps.<\/p>\n

We have developed an innovative approach based on deep neural networks and time-series analysis of Sentinel-2 multispectral imagery (10-meter resolution). This method consists of two complementary models:<\/p>\n

    \n
  1. A classification model<\/strong> that differentiates optically shallow waters from deeper areas.<\/li>\n
  2. A regression model<\/strong> that accurately estimates water depth in optically shallow zones.<\/li>\n<\/ol>\n

    This project has enabled the Arctus team to develop robust and adaptable satellite-based bathymetry solutions. Our tools make it possible to estimate coastal water depth without prior in situ data, paving the way for more efficient and accessible marine monitoring.<\/p>\n
