Orthophoto of the Czech Republic - Vlašim 0-6

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.本数据集为采用8位色彩制式的数字化近乎无缝的捷克共和国正射影像（orthophoto）。该栅格图像Ortofota ČR的像素在地形中平面上对应的地面采样距离分别为：东带0.200米，西带0.125米。捷克共和国正射影像的位置精度持续提升，其以平均位置误差作为精度表征指标；2019至2020年间，该误差取值区间为0.20至0.21米。2021年度捷克共和国正射影像的精度评估工作尚未完成。Orthofoto ČR 以JPEG（JPG）图形栅格格式进行分发，每个分发单元对应覆盖2.5×2平方千米的地表区域，遵循SM 5分幅规范。
