Orthophoto of the Czech Republic - Karlovy Vary 4-3

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.捷克共和国数字化无缝正射影像（orthophoto）采用8位色深。Ortofota ČR作为捷克官方正射影像的栅格数据，其单个像素对应的地面采样距离，东带为0.200米，西带为0.125米，该参数对应地形中平面的实地尺度。捷克正射影像持续提升定位精度，其精度以平均定位误差作为表征指标；2019至2020年间，该误差值介于0.20至0.21米之间。2021年捷克正射影像的精度评估工作尚未完成。Orthofoto ČR以JPG图形栅格格式分发，其分发单元为SM 5分幅，每个分幅对应实地2.5×2千米的范围。
