Orthophoto of the Czech Republic - Žlutice 1-9

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.本数据集为捷克共和国数字化、视觉上近乎无缝的8位色深正射影像（orthophoto）。捷克正射影像（Ortofota ČR）的栅格图像像素对应地形中平面上东带0.200米、西带0.125米的地表范围。捷克共和国正射影像的位置精度持续提升，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2.5×2千米的地表范围，采用SM 5分幅规格。
