Orthophoto of the Czech Republic - Hranice 4-7
收藏资源简介:
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.
本数据集为捷克共和国数字化近乎无缝拼接的8位色彩正射影像(orthophoto)。该捷克正射影像项目(Ortofota ČR)的栅格图像中,单个像素对应地形中间平面上0.200米(东带)或0.125米(西带)的地面采样尺度。捷克正射影像的平面位置精度持续优化,其以平均平面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至0.21米。2021年捷克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,其分发单元对应2.5×2千米的地形范围,采用SM 5分幅(SM 5 clade)。
