Orthophoto of the Czech Republic - Kamenice nad Lipou 1-4
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正射影像(orthophoto),采用8位色彩分级。该栅格图像Ortofota ČR的单个像素在地形中平面上对应0.200米的地面覆盖范围(东区波段),西区波段则对应0.125米的地面覆盖范围。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年期间,该平均位置误差介于0.20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,其分发分幅单元的尺寸对应2.5×2千米的地面覆盖范围,归属SM 5级分类。
