Orthophoto of the Czech Republic - Žatec 0-0

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近乎无缝的数字化正射影像（orthophoto），采用8位色彩模式。该光栅图像（Ortofota ČR）的像素对应地形中平面的实地面积分别为：东波段0.200米，西区域0.125米。捷克正射影像的位置精度持续优化，以平均位置误差作为衡量指标，2019至2020年间该误差范围为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。捷克正射影像以JPG图形光栅格式分发，其分发单元为对应实地2.5×2公里范围的SM 5分幅。
