Orthophoto of the Czech Republic - Mimoň 3-7

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.本数据集为覆盖捷克共和国的近乎无缝数字化正射影像（orthophoto），采用8位色彩深度。这款名为Ortofota ČR的栅格图像，其像素对应地形中平面的地面面积：东带的像素分辨率为0.200米，西带则为0.125米。该捷克正射影像的定位精度持续优化，以平均定位误差作为精度表征指标；2019至2020年间，其平均定位误差区间为0.20至0.21米。2021年该正射影像的精度评估工作尚未完成。本数据集以JPG图形栅格格式进行分发，每个分发单元对应地面2.5×2千米的范围，适配SM 5分幅体系。
