Orthophoto Samkom Rona F405 E18 1961

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: Covers areas that mainly consist of dense and scattered settlements and agricultural areas. Ground resolution is usually > 0.15 – 0.25 m. Accuracy ± 0.50 m.正射影像（Orthophoto）具有与地图一致的几何特性，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标准。 该类正射影像的参数如下： 覆盖区域以密集散布的居民点与农业用地为主； 地面分辨率通常大于0.15米且不超过0.25米； 定位精度可达±0.50米。
