Orthophoto of the Czech Republic - Brno 9-4

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位色彩深度的数字化近乎无缝的捷克共和国正射影像图。捷克正射影像图（Ortofota ČR）的栅格图像单个像素对应地形中部平面下的地面覆盖范围，东波段为0.200米，西分区则为0.125米。捷克共和国正射影像图的位置精度持续优化，其精度以平均位置误差为表征指标，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图的精度评估工作尚未完成。Orthofoto ČR 以JPG图形栅格格式进行分发，分幅单元对应2.5×2千米的地面范围，采用SM 5 clade分幅规则。
