Orthophoto of the Czech Republic - Veselí nad Lužnicí 2-2
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.
捷克共和国数字化近乎无缝的8位色彩深度正射影像(orthophoto)。该栅格图像Ortofota ČR的像素对应地形中平面的区域面积,「东」波段单像素为0.200平方米,「西」分区单像素则为0.125平方米。捷克共和国正射影像的位置精度以平均位置误差为核心表征指标,并处于持续优化状态;2019至2020年间,该平均位置误差的区间为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。Orthofoto ČR以JPG图形栅格格式进行分发,其分发单元的尺寸对应2.5×2千米的地形区域,归属于SM 5类(clade)。
