[Qgis-user] Placing group of image at once

[Karlo no Dabas maajas]

Hi,

First of all – are You using JPG or PNG format images. Your text is a 
bit confusing.

JPG images are associated with JGW or WLD _world_ _format_ files.

XML can contain anything. Provide example.

Good luck,
Kārlis

> Our team is currently working on a project to reconstruct the railways

>   * *GeoTIFF method*: With over 500,000 images, manually georeferencing
>     each one is not feasible.
> 
> So I would like to ask for your advice:

>   * Are we on the right track with our approach?
>   * Which method would you recommend in our case?
>   * Do you know of any way to automate the image placement and
>     orientation based on our XML data?
>   * Would it be possible to handle this through the Python console or
>     using PyQGIS?

> Any guidance or suggestions would be greatly appreciated.
