Orthophoto of the Czech Republic - Žatec 0-1
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.
本数据集为采用8位色彩深度的捷克数字化近乎无缝正射影像(orthophoto)。该栅格影像Ortofota ČR的单像素对应地形中平面的地面覆盖尺度:东带(East band)为0.200米,西带(West zone)为0.125米。捷克正射影像的位置精度持续优化,其精度以平均位置误差为核心表征指标;2019至2020年间,该误差区间为0.20至0.21米。2021年捷克正射影像的精度评估工作尚未完成。Orthofoto ČR以JPG格式的栅格图形文件进行分发,每个分发单元对应SM 5 clade下2.5×2公里的地形范围。
