Orthophoto Bygland-Åseral-Lyngdal-Lindesnes-Evje 1988

Orthophoto has the same geometric properties as a map for all objects located at ground level and can be linked to a reference system. Ground resolution of orthophoto varies and is stated in the metadata. For projects completed before 2020, the accuracy will range from 0.5-2 m depending on ground resolution and used terrain model. From 2020, the accuracy of the product is stated in the metadata information.正射影像（Orthophoto）对所有位于地面的物体具备与地图一致的几何特性，且可关联至参考坐标系。正射影像的地面分辨率（Ground resolution）并非固定值，其具体数值会在元数据（metadata）中注明。对于2020年前完成的项目，其精度范围为0.5至2米，具体取决于地面分辨率与所采用的地形模型。2020年起，该产品的精度将直接在元数据信息中载明。
