Orthophoto Hammerfest 2010

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特性，可接入参考坐标系。正射影像可根据不同应用需求划分为多种适配标准。Ortho 10型正射影像：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用地，其地面分辨率通常为0.04–0.15米，定位精度为±0.35米。
