Orthophoto Agder 2019

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属性，可与参考坐标系关联。正射影像可依据不同应用需求划分为多种适配标准。Ortho 10标准正射影像：通常覆盖对定位精度与高分辨率有较高要求的城市区域及开发建设区域，其地面分辨率通常介于0.04至0.15米，定位精度为±0.35米。
