Convert coordinates from OSGB to WSG84 Northern Ireland

RobertLea

Hello

I am trying to convert Northern Irish postcode data from OSGB 1936 to WSG84 including the coordinates but I'm having no luck. I've tried using the project tool but I don't really understand how the datum selection works for transformation. I keep getting an error stating: invalid extent for output coordinate system.

Any help on this would be greatly appreciated.

Hi Robert,

We use a tool called Datum Pro to convert coordinates http://www.geomatix.net/datumpro/ as we receive data in a multitude of datum.

Datum Pro has the following options for OSGB to WSG84:
OSGB 1936 to WSG84 (Petroleum)
OSGB 1936-1 to WSG84
OSGB 1936-2 to WSG84
OSGB 1936-3 to WSG84
OSGB 1936-4 to WSG84
OSGB 1936-5 to WSG84

If you don't have many coordinates, let me know what you need conveting and I can run it for you.
