Orthophoto of the Czech Republic - Nymburk 3-1

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.捷克共和国近乎无缝的数字化8位色彩正射影像（orthophoto）。该栅格图像Ortofota ČR的像素在地形中间平面上对应的实地分辨率分别为：东波段（East）0.200米，西区域（West zone）0.125米。捷克共和国正射影像的位置精度正持续提升，其以平均位置误差作为精度表征指标，2019至2020年间该误差的取值范围为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。Orthofoto ČR以JPG图形栅格格式进行分发，其分发单元对应实地范围为2.5×2千米，采用SM 5 clade幅面。
