Orthophoto Hedmarken towns GSD7 temporarily 2021

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（Temporary orthophoto）是正射影像（orthophoto）的预交付成果，用于地图构建管控作业过程中。该产物由自动化方式生成，精度低于最终版正射影像。针对所有地表地物，临时正射影像具备与地图一致的几何属性，且可接入参考坐标系。临时正射影像的地面分辨率区间为0.04米至0.5米。此前，临时正射影像曾被称为校正影像（rectified images）。
