Orthophoto of the Czech Republic - Most 7-9

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.捷克共和国数字化无缝正射影像（orthophoto）采用8位色彩模式。该栅格影像Ortofota ČR的像素对应地形中平面的实地面积，其中东带像素对应0.200米范围，西带则对应0.125米范围。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，该误差值介于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。Orthofoto ČR以JPG图形栅格格式分发，其分发单元为符合SM 5分幅标准、对应实地2.5×2公里范围的图幅。
