Orthophoto of the Czech Republic - Blansko 2-6

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位色彩深度的数字化近乎无缝正射影像（orthophoto），覆盖捷克共和国全境。该栅格图像即捷克正射影像（Ortofota ČR），其单个像素在地形中部平面上分别对应东带0.200米、西带0.125米的实地面积。捷克共和国正射影像的位置精度持续提升，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米至0.21米之间。2021年该正射影像的精度评估工作尚未完成。捷克正射影像（Orthofoto ČR）以JPG图形栅格格式进行分发，其分发单元的尺寸对应2.5×2千米的实地范围，归属于SM 5类别。
