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.
