Orthophoto of the Czech Republic - Třešť 0-8

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.覆盖捷克共和国的数字化近乎无缝8位色彩深度正射影像（orthophoto）。此捷克正射影像（Ortofota ČR）的栅格图像（raster image）中，单个像素分别对应"东"波段下0.200米、"西"分区下0.125米的地表中间平面覆盖面积。该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，该误差值介于0.20米至0.21米之间。2021年该捷克正射影像的精度评估工作尚未完成。该捷克正射影像（Orthofoto ČR）以JPG图形栅格格式进行分发，其分发单元采用SM5级分幅，单个单元对应2.5×2千米的地表范围。
