Figures for "Improving Satellite Monitoring of Armed Conflicts"

Figure 1. From space, VHR imagery from Planet and Maxar reveals the landscape effects of Russia'’s invasion of Ukraine. 1. Cars waiting at the Ukrainian-Hungarian border (WorldView-3/Maxar); 2. Active fires in Chernihiv (PlanetScope2022/03/21); 3a. The North Crimean Channel without water preinvasion (PlanetScope-2022/02/21); 3b. Filled with water post-invasion (PlanetScope-2022/03/24); 4. Burning apartment buildings in Mariupol (WorldView-3/Maxar). Maxar imagery was obtained from https://www.maxar.com/ on 5 April 2022. PlanetScope data were obtained through University of Copenhagen license agreement PL0030875_2021/2022.

Figure 2. A village and surrounding farmland in Ukraine'’s Lviv Oblast are more difficult to discern in imagery from medium-resolution civilian satellites Landsat 8 (USGS, 2021/05/04) and Sentinel-2 (ESA, 2021/05/11) than in commercial VHR imagery from Dove/PlanetScope (2021/05/09) and SkySat (2021/05/09), both of which belong to Planet. Landsat 8 and Sentinel-2 data are available via https://glovis.usgs.gov. PlanetScope data were obtained through University of Copenhagen license agreement PL-0030875_2021/2022. SkySat data were obtained by special request from Planet.
