Orthophoto 32VNM 5 June 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. Satellite images used in Norway in images as overview maps. Ground resolution ranges from 2.5 – 30 m. Accuracy 10 – 300 m.正射影像（Orthophoto）具备与地图一致的几何属性，且可与参考坐标系建立关联。 正射影像可依据不同应用场景划分为多种适配的标准。 挪威将此类卫星影像用作概览地图。 地面分辨率范围为2.5~30米，精度范围为10~300米。
