The AI4EO challenge with UNOSAT addressed building-footprint mapping in Iraq, in support of reconstruction and census planning.<\/p>\n\n\n<h2>Our contribution<\/h2>\n\n\n<p>Alessandro Patruno and Andrey Malakhov participated as Team Zephyros in the AI4EO initiative. Their work explored machine-learning workflows for distinguishing buildings from their surroundings in satellite data.<\/p>\n\n\n<h2>Technical approach<\/h2>\n\n\n<p>Building-footprint segmentation using Sentinel-1 radar data in VV\/VH polarisations and WorldView optical imagery. The task connects image processing, machine learning and geospatial analysis across large areas.<\/p>\n\n\n<h2>Why it matters<\/h2>\n\n\n<p>The work demonstrates how scientific computing can turn Earth-observation imagery into information relevant to humanitarian and environmental questions.
