Orthophoto of the Czech Republic - Kralupy nad Vltavou 8-9

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.捷克共和国数字化无缝正射影像（orthophoto）采用8位色彩深度。捷克正射影像（Ortofota ČR）的栅格图像中，东部投影带的地面采样距离为0.200米，西部投影带则为0.125米，对应地形平均高程面的地面范围。该捷克正射影像的定位精度持续提升，以平均定位误差作为核心表征指标；2019至2020年间，其平均定位误差介于0.20米至0.21米之间。2021年该正射影像的精度评估工作尚未完成。捷克正射影像（Orthofoto ČR）以JPG图形栅格格式进行分发，每个分幅单元对应地面2.5×2千米的范围，采用SM 5分幅标准。
