Orthophoto of the Czech Republic - Dobříš 8-2

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.捷克共和国几乎无缝的数字化8比特色彩正射影像（orthophoto）。捷克正射影像（Ortofota ČR）的栅格图像中，单个像素对应地形中间平面上的地表区域，东区波段为0.200平方米，西区波段则对应0.125平方米。该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年间该误差范围为0.20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（Ortofota ČR）以JPG图形栅格格式进行分发，每个分发单元对应2.5×2千米的地表范围，采用SM 5 clade组织形式。
