I have multiple different historical aerial images from an ArcMap project and I want to "extract" somehow the present-day satellite image of their areas from Google Satellite.

So what I tried to do is, import Google Satellite with the XYZ Tiles Plugin, set the Coordinate Reference System (CRS) to DHDN / 3-degree Gauss-Kruger zone 4 (EPSG:31468), which is the CRS from the images, and saved the area with the Layer --> Save As functionality, using the coordinates of the images as north, east, south, west.

However, this does not work. I either get a blank (white) image or the image is of a completely different location and if I just import the image into QGIS it is also not at the right location.

Yet, when I import the image into ArcMap it is at the correct position.

The output of gdalinfo on one of the images is:

gdalinfo 1978-03.tif

As I have zero experience with ArcMap, I thought about using QGIS for this task. Furthermore, I can only use ArcMap at my University.

  • Yes, it somewhat is, however, I realized that I don't need to import the historical images to QGIS, instead I just need the (correct) coordinates to export the present-day images.

In that case it is better to export the visual content of your map canvas in QGIS: Project->Import/Export->Save Map as Image. Don't forget to check the "Append georeference information" Checkbox: https://youtu.be/xY-JR-mr57Y

I fixed the problem by importing the images to ArcMap and then exporting them without generating the auxiliary files.
