Orthophoto of the Czech Republic - Vranov 7-0

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.本数据集为近乎无缝的捷克共和国数字正射影像，采用8位色彩深度。捷克正射影像（Ortofota ČR）的栅格单像素对应地形中平面范围内的地面范围：“东部”波段的单像素对应0.200米，“西部”区域则对应0.125米。该正射影像的位置精度持续提升，以平均位置误差作为精度表征指标；2019至2020年间，其平均位置误差介于0.20至0.21米之间。2021年该正射影像的精度评估工作尚未完成。该捷克正射影像以JPG图形栅格格式进行分发，分发单元采用SM 5分幅标准，每个单元对应地面2.5×2千米的范围。
