Orthophoto Numedal water reservoir 2022

Temporary orthophoto is a preliminary delivery of an orthophoto that is used during the work with control of map construction. The product is automatically generated and has a lower accuracy than the final orthophoto. Temporary orthophoto has the same geometric properties as a map for all ground-level objects and can be linked to a reference system. Ground resolution of orthophoto ranges from 0.04 m to 0.5 m. Previously, temporary orthophotos were called rectified images.临时正射影像图（Temporary Orthophoto）是正射影像图（Orthophoto）的初步交付成果，用于地图制作管控作业过程中。该成果为自动生成，其精度低于最终版正射影像图。 临时正射影像图针对所有地面物体，具备与地图一致的几何属性，且可接入参考坐标系。 该临时正射影像图的地面分辨率范围为0.04米至0.5米。此前，临时正射影像图曾被称为校正影像（Rectified Images）。
