Orthophoto of the Czech Republic - Domažlice 0-9
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.
本数据集为捷克共和国8位色彩深度的近乎无缝数字正射影像。该栅格影像Ortofota ČR的地面分辨率在地形中平面上,东带为0.200米,西带则为0.125米。捷克共和国正射影像的位置精度持续提升,其精度以平均位置误差为核心表征指标;2019至2020年间,该误差值介于0.20米至0.21米之间。2021年捷克共和国正射影像的精度评估工作尚未完成。Orthofoto ČR 采用JPEG(JPG)图形栅格格式分发,每个分发单元对应实地2.5×2千米的范围,遵循SM 5 clade规格。
