Orthophoto of the Czech Republic - Chomutov 4-4

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.本数据集为捷克共和国数字化无缝正射影像（orthophoto），采用8位色彩深度制式。该栅格图像（Ortofota ČR）的像素对应地形中平面的地面范围分别为：东带0.200米，西带0.125米。捷克正射影像的位置精度持续提升，其精度以平均位置误差为表征指标；2019至2020年间，该误差区间为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。捷克正射影像以JPG图形栅格格式进行分发，每个分发单元对应地面范围为2.5×2千米，采用SM 5级分幅制式。
