Orthophoto of the Czech Republic - Tišnov 2-4
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.
本数据集为采用8位色彩深度的捷克共和国近乎无缝数字正射影像。其栅格图像(捷克正射影像Ortofota ČR)在地形中部基准面上的地面采样分辨率分别为:东波段0.200米,西区域0.125米。该捷克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参数;2019至2020年期间,其平均位置误差区间为0.20米至0.21米。2021年度该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,分幅单元的尺寸对应实地2.5×2千米范围,隶属于SM 5分级。
