Digital seemingly seamless orthophoto of the Czech Republic in a 8-bit color scale. The pixel of the raster image Ortofota ČR displays 0.200 m (band „East), resp. 0.125 m ("West" zone) of the area in the middle plane of the terrain. The orthophoto of the Czech Republic is constantly improving its positional accuracy characterized by a mean positional error, this error ranged from 0.20 to 0.21 m in the years 2019 - 2020. The evaluation of the accuracy of the orthophoto of the Czech Republic in 2021 has not yet been completed.
