Orthophoto of the Czech Republic - Znojmo 4-3

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无缝正射影像（orthophoto），覆盖捷克共和国全境。该栅格图像为捷克正射影像（Ortofota ČR），其单个像素对应地形基准面内0.200米的地面范围（东波段），西区域的像素对应地面范围则为0.125米。捷克共和国正射影像的位置精度持续提升，以平均位置误差为评价指标，2019至2020年间该误差范围为0.20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。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2.5×2千米的地面范围，对应SM 5 clade。
