projection transform with datum shift grid

Feb 12, 2014 at 4:16 PM
Does anyone know if I can supply a datum grid file to to make my transform from wgs84 to OSGB36 more accurate?

I've read on the forum that there are some concerns about accuracy? are these well founded or not?

No, you can't.
I roughly remember having fixed some transformation issues related to OSGB36, but that may have been in a different life.
If you have issues with the results using Proj.Net, you can change the build configuration to ...DSProjections. You will then use a different projection library.
