Coordinate system British National Grid Long/Lat (OSGB 36) [EPSG: 4277] to British National Grid (OSGB 36) [EPSG: 27700]

Hello All,

British National Grid Long/Lat (OSGB 36) [EPSG: 4277] seems to be missing from FME's suite of coordinate systems - or am I mistaken?

I have a table with Longitude and Latitude data in this projection and I want to create points from them, and then convert them to British National Grid (Meters) (OSGB 36) [EPSG: 27700]. I can try to use the Reprojector transformer, but I can't see EPSG: 4277 anywhere.

Is there anything which I could use instead? Or is there another solution such as creating a custom coordinate system?

Many thanks,

Jane

Do you have ArcGIS installed on the same machine? If you do, you can use the EsriReprojector transformer

Many thanks for this - no, I don't, but I have QGIS (though I have only dabbled with it) which may have similar? My problem is, though, that while I can transform the data in MapInfo, I would really like to be able to create a workspace in FME (as I have several tables) so I can run the process repeatedly.

Many thanks,

Jane

The EsriReprojector is a transformer within FME that uses the Esri libraries, not much help for you though.

 

 

You should be able to create a custom coordinate system. This link may help

Thank you, that will be really useful when we get the new version.
