Orthophoto of the Czech Republic - Vrchlabí 5-6

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无缝正射影像（orthophoto）。该栅格影像Ortofota ČR的单个像素对应地面中间平面上的实地范围：东部波段为0.200米，西部区域为0.125米。捷克正射影像的位置精度持续优化，其精度以平均位置误差作为衡量指标：2019至2020年间，该误差范围为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。Orthofoto ČR以JPG图形栅格格式进行分发，单个分发单元对应实地2.5×2千米的范围，采用SM 5分幅制式。
