Orthophoto of the Czech Republic - Veselí nad Lužnicí 1-9
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.
本数据集为采用8位色彩深度的捷克数字化无缝正射影像图(orthophoto)。该栅格影像(Ortofota ČR)的单个像素对应地面平均高程面上0.200米的东向波段范围,对应西向分区则为0.125米的地表范围。捷克正射影像图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,该误差区间为0.20至0.21米。2021年捷克正射影像图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,其分发单元为对应2.5×2千米地表范围的SM 5 clade。
