Orthophoto of the Czech Republic - Tachov 8-6

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位色彩深度的捷克共和国近乎无缝数字化正射影像（orthophoto）。栅格影像Ortofota ČR的单个像素对应地形中平面上0.200米（东带）与0.125米（西带）的地表范围，分别对应东、西两个分区。捷克正射影像的位置精度正持续优化，其以平均位置误差作为精度表征指标；2019至2020年间，该误差区间为0.20米至0.21米。2021年度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，分发单元采用SM5分幅规格，单幅对应地表2.5×2公里的范围。
