Orthophoto of the Czech Republic - Ctiboř 3-8
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.
本数据集为采用8位色彩深度的捷克数字无缝正射影像(orthophoto)。该栅格图像Ortofota ČR的单个像素,在地形中平面上分别对应0.200米(东带)与0.125米(西带)的地面采样范围。捷克正射影像的位置精度持续提升,其位置精度以平均位置误差为表征指标;2019至2020年间,该误差的取值范围为0.20至0.21米。2021年捷克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,其分发单元为覆盖2.5×2千米地表范围的图幅,隶属于SM 5 分区(clade)。
