Orthophoto of the Czech Republic - Břeclav 6-6
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位色彩深度的数字化近乎无缝的捷克共和国正射影像(orthophoto)。该栅格影像(Ortofota ČR,即捷克正射影像)的单个像素,在东部波段对应地面中平面上0.200米的地表范围,在西部分区则对应0.125米的地表范围。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衡量指标:2019至2020年间,该误差值介于0.20至0.21米之间。2021年度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,每个分发单元对应地表2.5×2千米的范围,采用SM 5分幅规格。
