Orthophoto of the Czech Republic - Humpolec 2-4
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.
捷克共和国数字化近乎无缝的8位色阶正射影像(orthophoto)。该栅格数据集Ortofota ČR的像素在地形中平面上对应的实地尺寸分别为:东波段0.200米,西区域0.125米。捷克正射影像的位置精度持续提升,其以平均位置误差为衡量指标:2019至2020年间,该误差范围为0.20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图形栅格格式进行分发,分幅单元的尺寸对应实地2.5×2千米,归属于SM 5分级。
