DESCRIPTION:This study analyzes OpenStreetMap contributions in Ukraine sin
 ce the February 2022 invasion\, crossing OSM building edits with ACLED con
 flict events and frontline geometries. Results reveal a sharp spike in edi
 ts following the invasion\, concentrated around Kyiv\, alongside a moderat
 e correlation between bombardment events and mapping activity. Spatial ana
 lysis shows contributions near the frontline even in occupied areas\, sugg
 esting deletions and ruin tags as proxies for physical destruction.
