Ortofoto Oslo Airport Gardermoen 2018

Orthophoto has the same geometric properties as a map and can be linked to a reference system. Orthophotos are divided into different orthophoto standards suitable for different purposes. Photo by Ortho 10: Normally covers urban areas and development areas where there is a need for good location accuracy and high resolution. The ground solution is usually 0.04 – 0.15 m. Accuracy ± 0.35 m.正射影像（Orthophoto）具备与地图一致的几何特性，且可与参考坐标系关联。 正射影像可根据不同应用场景划分为多种不同的标准规格。 Ortho 10规格正射影像： 该类影像通常覆盖对定位精度与高分辨率有较高要求的城市区域与开发用地。 其地面分辨率通常为0.04–0.15米，定位精度为±0.35米。
