Orthophoto of the Czech Republic - Mladá Boleslav 2-9

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正射影像图（orthophoto）。捷克正射影像（Ortofota ČR）的栅格图像像素，对应地形中部平面上的实地面积分别为0.200米（东带）与0.125米（西带）。捷克正射影像的位置精度持续提升，以平均位置误差作为核心衡量指标；2019至2020年间，该误差区间为0.20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，分幅单元的实地覆盖尺寸为2.5×2千米，归属于SM 5 clade。
