Orthophoto of the Czech Republic - Vsetín 9-3

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位色彩深度的捷克共和国数字化无缝正射影像（orthophoto）。捷克正射影像（Ortofota ČR）的栅格图像中，单个像素对应地形中间高程平面上0.200米的范围（东波段），西波段单个像素则对应0.125米的地形范围。该正射影像的位置精度持续提升，以平均位置误差作为精度衡量指标；2019至2020年间，其平均位置误差区间为0.20至0.21米。2021年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图形栅格格式进行分发，以SM 5分幅作为分发单元，每个单元对应2.5×2千米的地形范围。
