Orthophoto Lofoten agglomeration 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）具备与地图一致的几何属性，且可接入参考坐标系。正射影像可依据不同应用需求划分出多种适配的标准类型。 Ortho 10型正射影像： 通常覆盖对定位精度与高分辨率有明确要求的城市建成区与开发区域。其地面采样间隔（ground solution）通常为0.04至0.15米，定位精度可达±0.35米。
