Orthophoto of the Czech Republic - Liberec 3-7

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.本数据集为覆盖捷克共和国的数字化无缝正射影像（orthophoto），色彩深度为8位。该栅格影像（捷克正射影像Ortofota ČR）在地形中平面上的地面采样像素尺寸分别为：东带（East band）0.200米，西带（West zone）0.125米。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作为表征指标；2019至2020年间，该误差值介于0.20米至0.21米之间。2021年度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图形栅格格式分发，分幅单元对应实地2.5×2千米的范围，遵循SM 5 clade规范。
