Orthophoto of the Czech Republic - Vsetín 5-4

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捷克共和国正射影像。捷克正射影像（Ortofota ČR）的栅格图像像素对应实地0.200米（东带），西带则对应0.125米的实地范围，该对应关系基于地形中平面计算得出。该捷克正射影像的定位精度持续优化，以平均定位误差作为精度表征指标：2019至2020年间，其平均定位误差介于0.20至0.21米之间。2021年度该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图形栅格格式分发，其分发单元对应实地2.5×2千米的范围，归属于SM 5 幅组。
