Orthophoto of the Czech Republic - Mariánské Lázně 9-3
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位色彩深度的捷克共和国近乎无缝数字化正射影像(orthophoto)。捷克正射影像Ortofota ČR的栅格图像像素,东区波段对应地形中平面上0.200米的地面范围,西区波段则对应0.125米的地面范围。该捷克正射影像的位置精度持续提升,以平均位置误差为核心评价指标,2019至2020年间该误差区间为0.20至0.21米。2021年该捷克正射影像的精度评估工作尚未完成。Orthofoto ČR 以JPEG(JPG)图形栅格格式进行分发,每个分发单元对应2.5×2千米的地面范围,采用SM 5分幅类型(SM 5 clade)。
