Orthophoto of the Czech Republic - Bystřice nad Pernštejnem 0-2
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.
本数据集为捷克共和国数字化近乎无缝的8位色彩正射影像(orthophoto)。该栅格图像(Ortofota ČR)的单个像素,东区(East)波段对应地形中部平面上0.200米的区域,西区(West zone)则对应0.125米的区域。捷克共和国正射影像的位置精度持续提升,其精度以平均位置误差为表征指标:2019至2020年间,该误差范围为0.20米至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JPEG(JPG)图形栅格格式进行分发,其分发单元对应地形范围为2.5×2千米,归属于SM 5 clade。
