coordinate systemordnance-surveyqgis
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?
QGIS 3.0 has made it quite easy.
Use Create points layer from table tool (under Processing Toolbox | Vector creation).
Just assign X and Y fields and set appropriate Target CRS to reproject.
Assuming the data is really DD MM SS you can just add the data as follows
LAT,LON
42 46 05 N,86 12 04 E
I use spaces to separate DD MM SS and I assume since numbers are positive N,E. Other ways may work but I find this the fastest for me at least since using special characters takes typing time

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
