Orthophoto of the Czech Republic - Český Brod 7-0
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正射影像(orthophoto),采用8位色彩深度。该栅格影像Ortofota ČR的像素对应地形中平面上0.200米的地面范围(东带),西带则为0.125米。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评价指标;2019至2020年间,该误差介于0.20米至0.21米之间。2021年捷克正射影像的精度评估工作尚未完成。Orthofoto ČR以JPG图形栅格格式分发,其分发单元为对应2.5千米×2千米地形范围的瓦片,遵循SM 5 clade分区规范。
