Orthophoto of the Czech Republic - Jaroslavice 6-1
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近乎无缝的数字化8位色深正射影像(orthophoto)。其栅格图像(raster image)捷克正射影像(Ortofota ČR)的像素,在地形中平面处对应的实地边长分别为:"东区"波段0.200米,"西区"分区0.125米。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年间该误差的取值区间为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(Ortofota ČR)以JPG(JPEG)图形栅格格式进行分发,每个分发单元对应的实地覆盖范围为2.5×2千米,属于SM5级分幅。
