Orthophoto of the Czech Republic - Jáchymov 4-2

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.本数据集为覆盖捷克共和国的8位色彩深度近乎无缝数字正射影像（orthophoto）。该栅格影像（捷克正射影像Ortofota ČR）在地形中间平面处的地面采样距离，东带为0.200米，西带为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核心表征指标；2019至2020年间，该误差范围为0.20至0.21米。2021年度捷克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，其分发单元对应2.5×2千米的地面范围，隶属于SM 5分类。
