Orthofoto Rindal center 2011

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）具备与地图相一致的几何属性，且可与参考坐标系建立关联。正射影像可根据不同应用场景分为多种标准规格。 Ortho 10级正射影像： 该类影像通常覆盖对定位精度与分辨率均有较高要求的城市建成区与开发区，其地面分辨率通常为0.04~0.15米，平面定位精度可达±0.35米。
