Orthophoto of the Czech Republic - Ústí nad Labem 8-7

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位色彩深度的数字化近乎无缝的捷克共和国正射影像（Orthophoto）。该正射影像（Ortofota ČR）的栅格像素对应地形中平面的地面面积：东波段（East band）的像素分辨率为0.200米，西分区（West zone）则为0.125米。捷克共和国正射影像的位置精度持续优化，以平均位置误差作为精度衡量指标；2019至2020年间，该误差取值区间为0.20至0.21米。2021年捷克正射影像的精度评估工作尚未完成。该正射影像以JPG图形栅格格式进行分发，单个分发单元对应地面2.5×2千米的范围，采用SM 5分幅规范。
