Orthophoto of the Czech Republic - Litovel 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.
捷克共和国数字化无缝正射影像(orthophoto)采用8位色彩色阶。该栅格图像为捷克正射影像(Ortofota ČR),其像素对应地形中平面0.200米的地面范围(对应“东区”波段),西区波段则对应0.125米的地面范围。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衡量指标;2019至2020年间,该误差取值区间为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,其分幅单元在SM 5 clade下对应2.5×2千米的地面范围。
