Orthophoto of the Czech Republic - Nový Jičín 4-4

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.本数据集为捷克共和国数字化无缝正射影像（orthophoto），采用8位色彩深度。捷克正射影像（Ortofota ČR）的栅格像素对应地形中平面的地面范围为：东区0.200米，西区则为0.125米。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年间其误差区间为0.20至0.21米。2021年该正射影像的精度评估工作尚未完成。Orthofoto ČR以JPEG（JPG）图形栅格格式进行分发，每个分发单元对应2.5×2千米的地面范围，采用SM 5分幅规格。
