OSM contribution analysis in war time
Amine Chebil, Raphaël Bres, Malek Rihani
This study analyzes OpenStreetMap contributions in Ukraine since the February 2022 invasion, crossing OSM building edits with ACLED conflict events and frontline geometries. Results reveal a sharp spike in edits following the invasion, concentrated around Kyiv, alongside a moderate correlation between bombardment events and mapping activity. Spatial analysis shows contributions near the frontline even in occupied areas, suggesting deletions and ruin tags as proxies for physical destruction.
