Orthophoto of the Czech Republic - Bystřice pod Hostýnem 6-6
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.
本数据集为采用8位色深的捷克数字近乎无缝正射影像(orthophoto)。该栅格影像(Ortofota ČR)的单个像素对应地形中部平面上0.200米的地面范围(东带),西带则对应0.125米的地面范围。捷克正射影像的定位精度持续优化,其精度以平均定位误差为表征指标;2019至2020年间,该误差取值介于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。捷克正射影像以JPG图形栅格格式分发,其分幅单元对应2.5×2千米的地面范围,归属于SM 5层级。
