Orthophoto of the Czech Republic - Žacléř 6-7

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位色彩制式的数字化视觉近乎无缝的捷克共和国正射影像（orthophoto）。该栅格图像Ortofota ČR的单个像素，在地形平均高程面上，对应实地采样尺寸分别为：东波段（East）0.200米，西带（West zone）0.125米。捷克共和国正射影像的位置精度持续优化，其以平均位置误差作为精度表征指标；2019至2020年间，该误差取值区间为0.20至0.21米。2021年度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，单个分发单元对应的实地覆盖范围为2.5×2千米，采用SM 5分幅（SM 5 clade）规则。
