Orthophoto of the Czech Republic - Příbram 7-4

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正射影像（orthophoto）。该栅格图像（raster image）Ortofota ČR的单个像素对应地面中平面上0.200米的实地范围（对应「东区」波段），西区波段则对应0.125米的实地范围。捷克正射影像的位置精度持续提升，以平均位置误差作为精度表征指标：2019至2020年间，该误差区间为0.20米至0.21米。2021年度捷克正射影像的精度评估工作尚未完成。本次分发的Orthofoto ČR采用JPG图形栅格格式，分发单元对应2.5千米×2千米的实地范围，属于SM 5 clade分幅组。
