[Qgis-user] Georeferencing images

[Saber Razmjooei]

Hi

In the past, we developed a private plugin for georeferencing and
stitching multiple UAV images, similar to ENVI software workflow.

If you are dealing with an area where the elevation changes significantly,
best to follow the discussion here:
https://github.com/qgis/QGIS/pull/36385

As my colleague, Martin suggested, we may need to improve the current
Georeferencer plugin to make use of RPC_DEM.

Kind regards
Saber
