Orthophoto of the Czech Republic - Hrotovice 3-6

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图采用8位色彩深度。该栅格图像捷克正射影像（Ortofota ČR）的地面采样距离对应地形中平面的面积范围：东部波段为0.200米，西部区域为0.125米。捷克正射影像的位置精度持续优化，以平均位置误差作为精度评价指标：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。该正射影像以JPG图形栅格格式进行分发，其分发单元为符合SM 5 clade标准、对应地面2.5×2公里范围的图像块。
