Orthophoto of the Czech Republic - Volary 2-7

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位色彩深度的数字化近乎无缝的捷克共和国正射影像图。该栅格图像Ortofota ČR的单个像素对应地形中平面上0.200米的地面范围（东部波段），西部区域的像素则对应0.125米的地面范围。捷克共和国正射影像图的位置精度持续优化，以平均位置误差作为精度衡量指标，2019至2020年间该误差区间为0.20至0.21米。2021年捷克共和国正射影像图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，其分发单元的尺寸对应2.5×2千米的地面范围，归属SM 5分幅组。
