Orthophoto of the Czech Republic - Aš 6-8

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.捷克共和国数字化无缝正射影像（orthophoto）采用8位色彩深度。该栅格图像Ortofota ČR的像素，东区波段对应地形中平面下0.200米的实地范围，西区波段则对应0.125米的实地范围。该正射影像的位置精度持续优化，其以平均位置误差作为精度表征指标；2019至2020年间，该误差值介于0.20米至0.21米之间。2021年该正射影像的精度评估工作尚未完成。Orthofoto ČR以JPG图形栅格格式分发，其分发单元的尺寸对应实地2.5×2千米的范围，采用SM 5分幅规格。
