Orthophoto of the Czech Republic - Havlíčkův Brod 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)。该Ortofota ČR栅格图像的每个像素对应地形中平面范围内的地面采样尺寸分别为:东波段0.200米,西分区0.125米。捷克正射影像的位置精度持续优化,以平均位置误差作为核心表征指标;2019至2020年间,该误差的取值区间为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格式的图形栅格文件进行分发,其分发单元对应地面范围为2.5×2千米,采用SM 5 分区(SM 5 clade)。
