Orthophoto Rv2 Ullensaker-Kongsvinger 2004

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）与地图具备一致的几何属性，可与参考系统建立关联。正射影像可划分为适配不同应用场景的多种标准类型。其中Ortho 10型正射影像：通常覆盖对定位精度与高分辨率有较高需求的城区与开发区，其地面采样间距通常为0.04–0.15米，平面定位精度可达±0.35米。
