Orthophoto of the Czech Republic - Benešov 6-6

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位色彩深度的捷克数字无缝正射影像（orthophoto）。捷克正射影像（Ortofota ČR）的栅格图像像素分辨率为：东带（East band）对应0.200米的地面尺度，西带（West zone）则对应0.125米的地面尺度，该尺度对应地形中平面的区域范围。该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，平均定位误差介于0.20至0.21米之间。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（Orthofoto ČR）以JPG图形栅格格式进行分发，每个分发单元对应SM 5 clade规格下2.5×2平方千米的地面范围。
