Orthophoto of the Czech Republic - Domažlice 1-8
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.
捷克共和国近乎无缝的数字化正射影像(orthophoto)采用8位色彩深度。该栅格影像Ortofota ČR的单个像素,东带对应地形高程中平面上0.200米的地表范围,西带则对应0.125米的地表范围。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年度捷克共和国正射影像的精度评估工作尚未完成。Orthofoto ČR采用JPG图形栅格格式进行分发,其分发单元为SM 5 级分幅中对应2.5×2公里地表范围的区块。
