Orthophoto of the Czech Republic - Staré Město 2-7
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.
捷克共和国近乎无缝的数字化8位色彩正射影像图。该栅格影像(捷克正射影像Ortofota ČR)的单个像素对应地形中平面范围内,东投影带的地表覆盖面积为0.200平方米,西投影带则为0.125平方米。捷克共和国正射影像的位置精度持续提升,其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年捷克共和国正射影像的精度评估工作尚未完成。捷克正射影像(Orthofoto ČR)以JPG图形栅格格式进行分发,每个分发单元对应2.5×2公里的地表范围,归属SM 5分级。
