Orthophoto of the Czech Republic - Trutnov 4-2

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.本数据集为近乎无缝的捷克共和国数字正射影像（orthophoto），采用8位色彩量化尺度。该栅格图像Ortofota ČR的像素在地面中平面上，对应“东带”的地面区域尺寸为0.200米，“西带”则为0.125米。该捷克正射影像的定位精度以平均定位误差为表征指标，并持续得到优化；2019至2020年间，其平均定位误差区间为0.20米至0.21米。2021年该捷克正射影像的精度评估工作尚未完成。Ortofota ČR以JPG图形栅格格式进行分发，其分发单元采用SM 5分幅，尺寸对应地面2.5×2千米的范围。
