Orthophoto of the Czech Republic - Tišnov 9-0
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位色彩制式的捷克数字化近乎无缝正射影像(orthophoto)。捷克正射影像项目(Ortofota ČR)的光栅影像单个像素在地形中平面所对应的实地覆盖范围分别为:东带(East band)为0.200米,西带(West zone)为0.125米。捷克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,该误差区间为0.20至0.21米。2021年度捷克正射影像的精度评估工作尚未完成。Orthofoto ČR 以JPEG(JPG)图形光栅格式进行分发,分幅单元对应实地2.5×2千米的范围,适配SM 5分幅体系。
