Orthophoto of the Czech Republic - Písek 3-6

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.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（Ortoofota ČR）的栅格图像像素，对应地形中平面的地面覆盖范围分别为：东波段（East）0.200米，西区域（West zone）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评价指标；2019至2020年间，该误差区间为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。捷克正射影像（Ortoofota ČR）以JPEG（JPG）图形栅格格式分发，其分幅单元尺寸对应2.5×2千米的地形覆盖范围，采用SM 5 clade分幅形式。
