Orthophoto of the Czech Republic - Rakovník 6-9

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.本数据集为采用8位色彩深度的捷克共和国数字无缝正射影像（orthophoto）。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覆盖范围分别为：东波段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，其精度以平均位置误差为核心评价指标；2019至2020年期间，该误差范围处于0.20至0.21米之间。2021年捷克正射影像的精度评估工作尚未完成。该数据集以JPG图形栅格格式进行分发，单个分发单元的地面覆盖范围为2.5×2千米，适配SM 5 clade。
