Orthophoto of the Czech Republic - Tachov 7-0

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.捷克共和国数字化近乎无缝的正射影像（orthophoto）采用8位色彩深度规格。该栅格图像数据集（Ortofota ČR）的单个像素对应地形中间高程平面内的地表面积，其中东部波段为0.200米，西部区域为0.125米。捷克共和国正射影像的位置精度持续优化，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至0.21米之间。2021年捷克共和国正射影像的精度评估工作尚未完成。该数据集（Orthofoto ČR）以JPG图形栅格格式进行分发，其分发单元对应地表2.5×2千米的范围，归属SM5级分类组（clade）。
