Orthophoto Stavanger 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）具备与地图一致的几何特性，可关联至参考坐标系。正射影像可依据不同应用场景划分为多种适配的标准类型。 Ortho 10 类正射影像： 该类影像通常覆盖对定位精度与高分辨率有较高需求的城市区域与开发建设区域。其地面分辨率通常为0.04至0.15米，定位精度可达±0.35米。
