Orthophoto of the Czech Republic - Příbram 3-2

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近乎无缝数字化正射影像（orthophoto）。捷克正射影像（Ortofota ČR）的栅格像素对应地面中平面的区域尺度为：东带（East）对应0.200米，西区域（West zone）则对应0.125米。该正射影像的位置精度以平均位置误差为表征指标并持续提升；2019至2020年间，其平均位置误差区间为0.20至0.21米。2021年该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2.5×2千米的地形范围，采用SM 5分区（SM 5 clade）进行分幅。
