Orthophoto of the Czech Republic - Sobotka 3-6
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图(orthophoto)。该栅格影像Ortofota ČR的单个像素对应地面中间平面上的采样间距,东带为0.200米,西带则为0.125米。捷克共和国正射影像图的位置精度持续优化,以平均位置误差作为精度评价指标:2019至2020年间,该误差区间为0.20至0.21米。2021年该正射影像图的精度评估工作尚未完成。该正射影像图以JPG图形栅格格式分发,分发单元采用SM 5级分幅,单幅对应地面2.5×2千米的范围。
