Orthophoto of the Czech Republic - Hořovice 9-9

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.本数据集为捷克共和国数字化无缝正射影像（orthophoto），采用8位色彩制式。捷克正射影像（Ortofota ČR）的栅格图像像素，对应地形中平面的地面分辨率分别为：东带（East band）0.200米，西带（West zone）0.125米。该正射影像的位置精度持续优化，以平均位置误差为衡量标准；2019至2020年间，其平均位置误差介于0.20至0.21米之间。2021年度该正射影像的精度评估工作尚未完成。该正射影像以JPG图形栅格格式分发，其分发单元对应地面2.5×2千米的范围，采用SM 5幅型。
