Orthophoto of the Czech Republic - Uhlířské Janovice 8-4
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.
本数据集为捷克共和国数字化无缝正射影像(orthophoto),采用8位色彩模式。该栅格图像(raster image)Ortofota ČR的像素在地形中平面上,东部波段对应0.200米的地面覆盖范围,西部区域则对应0.125米的地面覆盖范围。捷克正射影像的位置精度持续优化,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米至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图形栅格格式分发,每个分发单元的影像覆盖2.5×2千米的地面范围,对应SM 5 组别。
