Hi All,

I’m looking for some advice - I have a set of non georeferenced aerial images that I need to georeference and mosaic together. Do you know if it is possible to do all of this within Grass GIS or what is the best tool to undertake this task?

Thanks in advance for your help

This you can do with
https://grass.osgeo.org/grass78/manuals/g.gui.gcp.html

Be sure to use the latest version of GRASS due to relevant bugfixes.

and mosaic together.

Here r.buildvrt is useful.

I’d say that all needed tools are there and working.

Hi,

Thanks for the reply earlier - is there a way of doing colour corrections/balancing of mosaic of images in grass gis also?

Thanks again for your help
