Orthophoto of the Czech Republic - Rakovník 8-2

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.本数据集为数字化近乎无缝的捷克共和国正射影像（orthophoto），采用8位色彩制式。该栅格图像（raster image）Ortofota ČR的像素对应实地范围为：东部波段对应0.200米，西部分区对应0.125米，采样基准为地形中部平面。捷克共和国正射影像的位置精度正持续优化，其精度以平均位置误差作为表征指标，在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图形栅格格式分发，每个分发单元对应实地2.5×2公里范围，属于SM5级分幅。
