Orthophoto of the Czech Republic - Jeseník 0-5
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位色彩深度的近乎无缝的捷克数字正射影像(orthophoto)。该栅格影像即捷克正射影像(Ortofota ČR),其像素在地形中平面上,东带对应0.200米的地面覆盖范围,西带则对应0.125米。该捷克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,其平均位置误差区间为0.20至0.21米。2021年该正射影像的精度评估工作尚未完成。捷克正射影像(Orthofoto ČR)以JPG图形栅格格式进行分发,其分发单元对应2.5×2千米的地形范围,采用SM 5分幅体系。
