Orthophoto Finnmark 2008

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: Round-trip photography covering the whole country. Ground resolution of these varies between 0.50, 0.40 or 0.25 m. From 2012, ground resolution applies 0.25 m for orthophoto from orbital photography. Accuracy ± 2 m for Ortophoto 50 (depends on the quality of the used height model)正射影像（Orthophoto）具备与地图一致的几何属性，且可关联至参考坐标系。正射影像可根据不同应用需求划分为多种标准类别。 正射摄影影像类型如下： 覆盖全国全域的往返航摄影像。 此类影像的地面分辨率涵盖0.50米、0.40米与0.25米三种规格。自2012年起，轨道摄影生成的正射影像统一采用0.25米的地面分辨率。 Orthophoto 50型正射影像的平面精度为±2米，该精度取决于所使用的高程模型质量。
