Orthophoto of the Czech Republic - Sobotka 5-0

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. Orthofoto ČR is distributed in graphic raster formats JPG in dispensing units with a size showing 2.5 x 2 km of terrain in the SM 5 clade.本数据集为捷克共和国无缝数字化正射影像（orthophoto），采用8位色彩深度。该栅格影像（Ortofota ČR）的地面采样距离对应地形中平面的实地尺寸，东带为0.200米，西带则为0.125米。捷克正射影像的位置精度持续优化，以平均位置误差作为精度表征指标；2019至2020年间，该误差区间为0.20至0.21米。2021年捷克正射影像的精度评估工作尚未完成。Orthofoto ČR 以JPG图形栅格格式分发，每个分发单元对应实地2.5×2公里的范围，属于SM 5分幅体系。
