Orthophoto of the Czech Republic - Prachatice 1-8

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.本数据集为采用8位色彩深度的数字化近乎无缝的捷克共和国正射影像（Ortofota ČR）。该栅格图像的单个像素，东部波段对应地形中间高程面内0.200米的实地范围，西部地区则对应0.125米的实地范围。捷克共和国正射影像的位置精度持续提升，其精度以平均位置误差作为表征指标；2019至2020年间，该误差的取值范围为0.20至0.21米。2021年该正射影像的精度评估工作尚未完成。该正射影像以JPEG（JPG）图形栅格格式进行分发，其分发单元的尺寸对应实地2.5×2千米的范围，采用SM 5幅型（SM 5 clade）标准。
