Orthophoto of the Czech Republic - Litoměřice 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位色彩制式的捷克共和国数字化近乎无缝正射影像（orthophoto）。该栅格影像Ortofota ČR的单个像素对应地形中平面上的地表范围，其中东波段为0.200米，西带为0.125米。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，该误差取值区间为0.20米至0.21米。2021年捷克共和国正射影像的精度评估工作尚未完成。Orthofoto ČR以JPG图形栅格格式分发，其分发单元的尺寸对应SM 5类别下2.5千米×2千米的地表范围。
