I have a couple of images that I have made with the service "maps made easy" but I have a problem. The images are projected with the CRS: "EPSG:4326, WSG 84"

My normal projection is "EPSG: 25833" so the images are slightly off in placement.

How can I reproject the images so they will fit?

I have tried to use this method, but I get an unreadable file back, I don't know what I am doing wrong. How to reproject a raster in QGIS?

  • Some more details on the parameters you handed the tool (raster -> projection -> transform/reproject would be useful. Also it would be nice to know, which data type your output has. Further noteworthy: QGIS is able to project data where it "lies", therefore reprojection is usually not needed. The differences most likely occure due to different data sources/sensors.

  • the data type of my starting map is TIF, i set the source SRS to: EPSG 4362 and my target SRS to: EPSG 4936. When i run the prosess (raster -> projection -> transform/reproject) it sais: "Invalid Layer: GDAL providor cannot open GDAL dataset" I get several files from the proses but i can't read any of them (file types are: TIF, ERS, AUX)

Datum EPSG:4326 differs from EPSG:25833, EPSG:4326 is World Geodetic System 1984 vs EPSG:25833 based on European Terrestrial Reference System 1989.

So, you have to implement geographic transformation first (raster -> projection -> transform/reproject as @Erik mentioned) between EPSG:4326, EPSG:4936:

Warp QGIS

and after that project to EPSG:25833:

  • Hello Jane, I have tried to change between EPSG:4326 to EPSG:4936, but i get the same message: "Invalid Layer: GDAL providor cannot open GDAL dataset". Do you know what is wrong?
