Orthophoto of the Czech Republic - Chomutov 4-7

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.捷克共和国数字化无缝正射影像（orthophoto）采用8位色彩深度。该栅格影像Ortofota ČR的单个像元，在地形平均平面范围内，东带地面采样距离为0.200米，西带则为0.125米。捷克共和国正射影像的位置精度持续优化，其精度以平均位置误差为衡量指标，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。Orthofoto ČR以JPG图形栅格格式分发，每个分发单元的影像覆盖2.5×2千米的地表区域，对应SM 5 clade。
