Where is the projection on the fly in QGIS?
You can also activate the projection “on the fly” (and then “OTF” will appear next to the EPSG projection at the bottom right corner of the main window). This can be useful as it allows QGIS to handle layers with different CRS and to show them simultaneously on the same map without having to manually change the CRS.
Where to find Ordnance Survey tif file in QGIS?
This way the .tfw and the .tif files are in the same directory and QGIS can use the information. In the QGIS main windows, go to . Browse to the MiniScale_(standard)_R17.tif file and click Open. The Ordnance Survey files are in the British National Grid projection.
How to save a layer definition in QGIS?

When do I change the CRS in QGIS?
Here you can set the CRS when you save your data. If you select a new CRS, this will transform the coordinates of the data the new coordinate system and save the result in appropriate file. Depending on what you select you will also get to specify the transformation method.

How does QGIS project data from another CRS?
What this means is that even if the data itself is in another CRS, QGIS can project it as if it were in a CRS of your choice. To enable “on the fly” projection, click on the CRS Status button in the Status Bar along the bottom of the QGIS window: In the dialog that appears, check the box next to Enable ‘on the fly’ CRS transformation.
Which is the best reference system for QGIS?
A Coordinate Reference System, or CRS, is a method of associating numerical coordinates with a position on the surface of the Earth. QGIS has support for approximately 7,000 standard CRSs, each with different use cases, pros and cons! Choosing an appropriate reference system for your QGIS projects…
