Ortofoto Bodø 2009

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，可关联至参考坐标系。正射影像依据不同应用需求分为多种适配的标准类型。其中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建成区与开发区域，其地面采样分辨率通常为0.04–0.15米，定位精度可达±0.35米。
