Orthophoto of the Czech Republic - Opava 5-0

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数字化近乎无缝的8位色彩正射影像（orthophoto）。该栅格图像（捷克正射影像Ortofota ČR）的像素在地形中平面内的地面采样间距分别为：东带0.200米，西带0.125米。该捷克正射影像的位置精度持续优化，以平均位置误差作为精度表征指标，2019至2020年间其误差区间为0.20至0.21米。该捷克正射影像2021年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，分发单元采用SM 5分幅，每个单元对应地面2.5×2千米的范围。
