Orthophoto of the Czech Republic - Liberec 7-4

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.捷克共和国数字化近乎无缝正射影像（orthophoto）采用8位色彩尺度。该栅格图像Ortofota ČR的单个像素对应地形中间平面的地面范围分别为：东区波段0.200米，西区波段0.125米。捷克共和国正射影像的位置精度持续优化，以平均位置误差作为精度衡量指标；2019至2020年间，该误差区间为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，每个分发单元对应SM 5分区下2.5×2平方千米的地面范围。
