Orthophoto of the Czech Republic - Uherský Brod 8-3
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位色彩模式的捷克共和国数字化无缝正射影像(orthophoto)。该捷克正射影像(Orthofoto ČR)的栅格图像(raster image)像素对应地面中平面的实地范围:东波段(East band)为0.200米,西区域(West zone)为0.125米。捷克共和国正射影像的位置精度持续提升,其以平均位置误差作为精度表征指标;2019至2020年间,该误差范围为0.20米至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。捷克正射影像以JPG图形栅格格式进行分发,每个分发单元对应实地范围为2.5×2千米,隶属于SM 5分幅类别。
