Orthophoto of the Czech Republic - Hlinsko 7-8
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数字无缝正射影像(orthophoto)。该栅格图像Ortofota ČR的单个像素对应地形基准面上的地表范围分别为:东带0.200米,西带0.125米。捷克正射影像的位置精度持续提升,其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。该捷克正射影像2021年度的精度评估工作尚未完成。Ortofota ČR以JPG图形栅格格式进行分发,其分发单元的图幅对应地面范围为2.5×2千米,采用SM 5 clade分幅规范。
