Orthophoto Svolvær-Helle 2012

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）与地图具备相同的几何特性，可与参考坐标系建立关联。正射影像可依据适用场景的不同划分为多种标准类型。Ortho 10级正射影像通常覆盖对定位精度与高分辨率有需求的城区及开发区域，其地面采样距离一般为0.04–0.15米，定位精度可达±0.35米。
