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.
捷克共和国数字化近乎无缝的8位色彩正射影像(orthophoto)。该栅格图像Ortofota ČR的像素,在地形中平面范围内对应0.200米的地面尺度,其中东部波段为0.200米,西部区域则为0.125米。这款捷克正射影像的位置精度持续提升,其精度以平均位置误差为表征指标;2019至2020年间,该误差区间为0.20至0.21米。2021年该捷克正射影像的精度评估工作尚未完成。Orthofoto ČR 以JPG图形栅格格式进行分发,其分发单元为符合SM 5分幅规范、对应2.5×2千米地面范围的图像块。
