Orthophoto of the Czech Republic - Aš 0-9

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）。该栅格影像为Ortofota ČR（捷克正射影像项目），其地面采样距离（Ground Sample Distance, GSD）分别为0.200米（东带）与0.125米（西带），对应地形中部平面内的地表覆盖范围。捷克共和国正射影像的位置精度持续提升，其精度以平均位置误差作为核心表征指标；2019至2020年间，该误差值介于0.20米至0.21米之间。2021年捷克共和国正射影像的精度评估工作尚未完成。Orthofoto ČR（捷克正射影像）以JPG图形栅格格式进行分发，分发单元采用SM 5分幅规格，单幅对应2.5×2千米的地表范围。
