Orthophoto of the Czech Republic - Pelhřimov 5-6
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.
捷克共和国数字化近乎无缝的8位色彩深度正射影像(Orthophoto)。该栅格图像捷克正射影像(Ortofota ČR)的单个像素,对应地形平均高程面上0.200米的范围(东区波段),西区波段则对应地形平均高程面上0.125米的范围。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表征指标;2019至2020年间,该误差的取值范围为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。捷克正射影像(Orthofoto ČR)以JPG图形栅格格式进行分发,每个分发单元对应2.5×2千米的地表范围,采用SM 5类规格。
