Orthophoto of the Czech Republic - Odry 5-1
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数字化近乎无缝的正射影像(orthophoto),采用8位色彩深度。捷克正射影像Ortofota ČR的栅格像素在地形中平面处的地面分辨率分别为:东带0.200米,西带0.125米。该正射影像的位置精度持续提升,以平均位置误差作为精度表征指标;2019至2020年间,其平均位置误差介于0.20至0.21米之间。2021年捷克正射影像的精度评估工作尚未完成。捷克正射影像Ortofota ČR以JPG图形栅格格式进行分发,其分发单元采用SM 5 分幅规格,每个单元对应2.5×2千米的地面范围。
