Orthophoto of the Czech Republic - Staré Město 8-9
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无缝正射影像(orthophoto),采用8位色彩深度。该栅格图像捷克正射影像(Ortofota ČR)的像素,在地形中平面上分别对应0.200米(东带)与0.125米(西带)的地面覆盖范围。该捷克正射影像的位置精度持续优化,以平均位置误差作为核心衡量指标;2019至2020年间,其平均位置误差区间为0.20米至0.21米。2021年该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(JPEG)图形栅格格式分发,每个分发单元对应SM 5 clade下2.5×2平方千米的地面范围。
