How to extract a projection from a raster file?
Extracts the projection of a raster file and writes it into a world file with extension .wld. This algorithm is derived from the GDAL srsinfo utility. 24.2.5.2.1. Parameters ¶
Why does QGIS use a non file raster layer?
Input raster The raster layer has to be file based, as the algorithm uses the path to the raster file as the location of the generated .wld file. Using a non-file raster layer will lead to an error. If this is activated a .prj file containing the projection information is also created.
What happens when you turn off projection in QGIS?
This means that when QGIS detects that you have loaded layers with different CRS, it will automatically re-project them back to a common CRS so they line up with each other. Click OK. Let’s turn-off the On-the-fly CRS transformation and see what happens. Click on the Current CRS text at the bottom-right corner.
