Orthophoto of the Czech Republic - Vimperk 4-5
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.
捷克共和国数字化近乎无缝的正射影像(orthophoto)采用8位色彩深度。Ortofota ČR的栅格图像中,单个像素分别对应地面中平面上0.200米的地表范围(东带)与0.125米的地表范围(西带)。该捷克正射影像的位置精度持续优化,以平均位置误差作为精度评价指标;2019至2020年间,该误差值介于0.20至0.21米之间。2021年度该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,分幅单元对应2.5×2千米的地表范围,属于SM 5分级。
