Orthophoto of the Czech Republic - Přimda 5-3

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无缝正射影像（orthophoto）。该栅格影像Ortofota ČR的像素对应实地0.200米（东区波段），西区波段则对应0.125米的实地范围，其空间分辨率基于地形中平面计算得出。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表征指标；2019至2020年间，该误差区间为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。Ortofota ČR以JPG图形栅格格式分发，每个分发单元对应实地2.5×2千米的范围，采用SM 5 clade规格。
