Orthophoto of the Czech Republic - Frýdlant 4-6

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.本数据集为捷克共和国数字化视觉无缝的正射影像（orthophoto），采用8位色深进行色彩表达。该栅格图像Ortofota ČR的像素在地形中间平面对应的地面分辨率为："东区"波段0.200米，"西区"分区则为0.125米。捷克正射影像的位置精度正持续优化，其以平均位置误差作为精度表征指标：2019至2020年间，该误差的取值区间为0.20米至0.21米。2021年捷克正射影像的精度评估工作尚未完成。捷克正射影像以JPG图形栅格格式分发，每个分发单元对应SM 5分幅下2.5×2千米的地面范围。
