Orthophoto of the Czech Republic - Moravská Třebová 7-9
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位色彩深度的数字化近乎无缝的捷克共和国正射影像(Orthophoto ČR)。该栅格图像Ortofota ČR的地面采样距离在地形中部平面下,东区波段为0.200米,西区波段为0.125米。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,该误差的取值范围为0.20米至0.21米。2021年捷克共和国正射影像的精度评估工作尚未完成。Orthofoto ČR以JPG图形栅格格式分发,每个分发单元对应2.5千米×2千米的地表范围,采用SM5分幅规范。
