Orthophoto of the Czech Republic - Děčín 2-4

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位色彩深度的捷克数字化近乎无缝正射影像（orthophoto）。捷克正射影像（Ortofota ČR）的栅格像素对应地面中间平面的面积：东波段为0.200米，西分区对应0.125米。该正射影像的位置精度持续提升，其以平均位置误差作为精度表征指标；2019至2020年间，该误差取值区间为0.20至0.21米。2021年捷克正射影像的精度评估工作尚未完成。该捷克正射影像以JPG图形栅格格式分发，每个分发单元对应2.5×2千米的地面范围，隶属于SM 5分类单元（clade）。
