Orthophoto of the Czech Republic - Jindřichův Hradec 1-1
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.
近乎无缝的数字化捷克共和国正射影像(orthophoto)采用8位色彩深度。捷克正射影像(Ortofoto ČR)的栅格图像像素,对应地形中平面的地面范围:东波段为0.200米,西分区则为0.125米。该正射影像以平均定位误差作为精度表征指标,定位精度持续提升;2019至2020年间,其平均定位误差区间为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(JPEG)图形栅格格式进行分发,其分发单元为SM 5分幅体系下对应2.5×2千米地面范围的图幅。
