Orthofoto Møre 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: 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，可与参考坐标系关联。正射影像可分为适配不同应用场景的多类标准。 正射影像摄影说明： 采用覆盖全域的往返式摄影作业。 此类影像的地面分辨率介于0.50米、0.40米或0.25米。 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。 Ortophoto 50的平面精度为±2米，该精度取决于所用高程模型的质量。
