I updated the tutorial in question. There was some problem in the previous
version : the modification of the PROJ_INFO file was not good and the grid
file needs to be in the nad directory of GRASS. The method explained by the
tutorial, needs the administrator rights on Linux.
Somebody knows more about the nadgrids specification in the PROJ_INFO file ?
I mean, how to set a grid which is not in the nad directory of GRASS ? If
there is this possibility, a simple normal user would be able to that.
You should be able to just put the full path in the PROJ_INFO file - does
that not work? If not can you post the contents of the PROJ_INFO file to
the list.
We should probably include the French gridshift file for datum
transformations NTF <--> RGF93 in the GRASS distribution, like we do for
the USA, Canada, New Zealand files. That would make it very easy to use.
How large is the file?
