I have created a basic QGIS project with a basemap and a point layer saved with CRS OSGB 1936/British national grid. When uploaded to Qfield, my actual location and the layers I have uploaded don't match. I presume this is a beginners CRS problem?

Almost certainly. Check under Project Properties, and then layer properties for each layer. If your base map is, for instance Google, in Project_Properties_Transformations you also need to have appropriate translations loaded.


The Transformations are added by pressing the green plus button. This opens the dialog below. Select your source CRS, which for Google is EPSG:3857. And your destination CRS, i.e. the CRS you use, for instance BNG (or more accurately, EPSG:27700).

  • Hi, I'm having a similar issue. When you say 'you also need to have appropriate translations loaded', how do you go about including them your qfield project ? Could you elaborate a bit ?
