Orthophoto of the Czech Republic - Šternberk 2-4

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.本数据集为采用8位色彩深度的捷克共和国数字化近乎无缝正射影像（orthophoto）。该栅格图像捷克正射影像（Ortofota ČR）的地面采样分辨率，在地形中平面的基准区域内，东侧波段对应0.200米的地面尺度，西侧区域则对应0.125米的地面尺度。捷克共和国正射影像的位置精度持续提升，其以平均位置误差作为精度表征指标；2019至2020年间，该误差值介于0.20米至0.21米之间。2021年捷克共和国正射影像的精度评估工作尚未完成。捷克正射影像以JPG（JPEG）栅格图形格式进行分发，每个分发单元为符合SM5标准的分幅，对应2.5×2千米的地面范围。
