Orthophoto of the Czech Republic - Nový Bor 6-5
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位色彩量程的捷克数字化近乎无缝正射影像(orthophoto)。栅格图像Ortofota ČR(捷克正射影像)的单个像素对应地表平均平面上0.200米(东投影带)或0.125米(西投影带)的地表面积。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,该误差区间为0.20米至0.21米。2021年度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,其分发单元为SM 5级分幅下对应2.5千米×2千米地表范围的图幅。
