Fig. 2: Damage estimates and UNOSAT labels for Chernihiv.
From: An open-source tool for mapping war destruction at scale in Ukraine using Sentinel-1 time series
Building damage estimate for Chernihiv thresholded with the standard confidence threshold of 0.655, aggregated over the first two years of conflict. For clarity, we only present the damage heatmap in the main figure, while three zoomed insets show building-level predictions and highlight some known limitations, such as missing building footprints (Inset A), issues with detecting all small structures (Inset B), and disagreements between UNOSAT points and building footprints (Inset C). Red dots represent UNOSAT annotations indicating buildings marked as either destroyed or severely damaged. The VHR satellite layer is displayed solely for visualization, all results are derived from 10 m-resolution Sentinel-1 images. Readers are encouraged to explore the maps on the interactive dashboard.
