Orthophoto Sel 2006

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）具备与地图一致的几何特性，可与参考坐标系（reference system）绑定关联。正射影像可根据不同应用场景划分为多种适配的标准类型。正射影像覆盖范围以密集分散的居民点与农业区域为主。其地面分辨率通常大于0.15–0.25米，精度为±0.50米。正射影像具备与地图一致的几何特性，可与参考坐标系绑定关联。正射影像可根据不同应用场景划分为多种适配的标准类型。正射影像覆盖范围以密集分散的居民点与农业区域为主。
