Orthophoto of the Czech Republic - Strakonice 8-7
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.
捷克共和国数字化无缝正射影像(orthophoto)采用8位色彩深度。该栅格图像(Ortofota ČR)的单个像素对应实地地形中平面范围内的面积,其中东部波段为0.200米,西部分区为0.125米。捷克共和国正射影像的位置精度持续优化,其精度以平均位置误差作为表征指标;2019至2020年间,该误差值处于0.20米至0.21米区间内。2021年度捷克共和国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,其分发单元为覆盖2.5×2千米实地范围的SM 5分幅区块。
