Orthophoto of the Czech Republic - Bystřice nad Pernštejnem 9-7
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.
本数据集为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。该栅格影像Ortofota ČR(捷克正射影像数据集)的地面采样间隔在地形基准面内为:东部波段0.200米,西部分区0.125米。捷克共和国正射影像的位置精度持续提升,以平均位置误差作为精度表征指标;2019至2020年间,该误差取值范围为0.20至0.21米。2021年度捷克共和国正射影像的精度评估工作尚未完成。Orthofoto ČR以JPG(JPEG)图形栅格格式分发,其分幅单元对应实地2.5×2千米的范围,属于SM 5 clade。
