Orthophoto of the Czech Republic - Dubá 4-9

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.捷克共和国的数字化且视觉上近乎无缝的8位色彩深度正射影像（orthophoto）。该栅格图像（捷克正射影像Ortofota ČR）的像素对应地面中间平面的区域范围，其中东区波段的像素对应0.200米的地面范围，西区波段则对应0.125米的地面范围。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为衡量指标，2019至2020年间该误差区间为0.20米至0.21米。2021年捷克共和国正射影像的精度评估工作尚未完成。捷克正射影像（Orthofoto ČR）以JPG图形栅格格式进行分发，其分发单元对应2.5×2千米的地面范围，采用SM 5分幅标准。
