Orthophoto of the Czech Republic - Praha 0-0
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无缝捷克正射影像(orthophoto)。捷克正射影像(Ortofota ČR)的栅格像素以地形中平面为采样基准,其中东区波段的单像素对应实地0.200米范围,西区波段则对应0.125米范围。该正射影像的位置精度持续优化,其精度以平均位置误差为表征指标;2019至2020年间,该误差取值区间为0.20至0.21米。2021年度该正射影像的精度评估工作尚未完成。Orthofoto ČR 以JPG图形栅格格式进行分发,其分发单元为SM 5分幅,每个分幅对应实地2.5×2千米的范围。
