I have a text file in which coordinates are in the OSGB36 National Grid reference system used in Great Britain, so the coordinates are not in longitude and latitude (e.g. coordinates look like this: SD481731, and are only in one column). I would like to display these points in QGIS 2.4.0. However, when adding a delimited text layer, it is mandatory to specify the X and the Y fields.

Can I circumvent this and display OSGB36 coordinates imported directly from one column in a text file?

  • set your crs to osgb36 add the x,y points in then change your coordinate system to wgs84 and export for lat/lng. – Mapperz Sep 16 '14 at 14:54

Okay I see SD481731 needs to be separated into Eastings and Northings

which is X=348100&Y=473100

For Lat/LNG https://www.google.co.uk/maps/place/54%C2%B009%2703.9%22N+2%C2%B047%2746.1%22W/@54.1636496,-2.7901201,13z/data=!4m2!3m1!1s0x0:0x0

You will need to do this to all your OS Grid References http://en.wikipedia.org/wiki/Ordnance_Survey_National_Grid

What you have are Ordnance Survey National Grid References. To batch convert these to Ordnance Survey Coordinates I'd suggest you have a look at NG Converter, see: http://digimap.edina.ac.uk/webhelp/os/data_information/os_data_issues/ng_converter.htm
