Orthophoto of the Czech Republic - Kladno 8-0

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.本数据集为采用8位色彩深度的近乎无缝数字化捷克共和国正射影像（orthophoto）。捷克正射影像（Ortofota ČR）的栅格图像像素，在地形中平面上对应的地面覆盖范围分别为：东带（East band）0.200米，西带（West zone）0.125米。该捷克正射影像的位置精度持续优化，其精度以平均位置误差为表征指标；2019至2020年间，平均位置误差区间为0.20至0.21米。2021年该捷克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，每个分发单元对应SM 5分级下2.5×2千米的地面范围。
