Orthophoto of the Czech Republic - Chomutov 4-1

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近乎无缝衔接的捷克共和国正射影像（orthophoto）。其栅格图像Ortofota ČR的像素在地形中平面上，分别对应0.200米的地面覆盖范围（对应"东"波段）与0.125米的地面覆盖范围（对应"西"带）。捷克共和国正射影像的位置精度持续优化，以平均位置误差作为精度表征指标：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。Orthofoto ČR以JPG图形栅格格式进行分发，分发单元的尺寸对应2.5×2千米的地形范围，属于SM 5 clade。
