Orthophoto of the Czech Republic - Bílovec 7-9

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.本数据集为采用8位色彩深度的捷克数字化近乎无缝正射影像（orthophoto）。该栅格影像Ortofota ČR的像素在地形中平面上，东带对应0.200米的地面范围，西带则对应0.125米的地面范围。捷克正射影像的定位精度持续提升，其以平均定位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年捷克正射影像的精度评估工作尚未完成。Orthofoto ČR 采用JPEG（JPG）图形栅格格式进行分发，其分幅单元的地面覆盖范围为2.5×2千米，适配SM 5幅型。
