Orthophoto of the Czech Republic - Prachatice 7-8

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位色彩深度的捷克共和国数字无缝正射影像（orthophoto）。该栅格影像Ortofota ČR的像素对应实地0.200米范围（东带），西带则对应0.125米范围，其采样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，该误差值区间为0.20至0.21米。2021年度捷克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，其分幅单元对应实地2.5×2公里的范围，采用SM 5分幅体系。
