Ah, that's right, forgot to mention, that's why I use the provincial GSB[1]
in BC for CSRS transformations.
The license is a little different =) You have to get written permission
(could be via email) to use the GSB in that FTP.

Hi,
I have been looking at that. If I understand, that grid is for the nad27
to nad83 (original). Updated version of nad83(csrs96) known as nad83csrs
or nad83(csrs98) are not included. I think the trx software is the
only ways out for those. I and sending email to see if other grids exist
The NTv2 GSB[1] for Canada is shared under the "Open Government License -
Canada"[2].
I made a request some years ago and they did it! So it's definitely a good
step forward.
I'm not a license guru so not sure if it can be packaged and redistributed
with FOSS (ie, QGIS or proj).
I know for

Maybe it would also be more user friendly, if QGIS would already deliver
the grid shift files for most countries. But that would bloat QGIS quite
a bit. The grid shift file for Switzerland (one of the smallest

Hi Nicolas and André,
To be honest I don't know much how you setup QGIS properly to use the
grid shift files. I just wanted to say that the support is there, but
probably needs some improvements or better explanation/documentation.
For my own country's date shifts, "it just works", probably

Hi Nicolas,
That is not exactly true.
QGIS can very well cope with grid-shift based transformations. This
requires an adequate grid shift file (a gsb file), which should be
placed in the folder share/proj
National mapping agencies typically provide these grid-shift files. As
an example, our
Hi,
It is my understanding that the parameters used in QGIS for that transformation
are not sufficient and will simply lead to a change in EPGS code number
with no actual changes to the coordinates.
If you are dealing with data in the 20k to 250k (like topo maps, SRTM), you can
go ahead with
simply save the layer as a new one. “save as”. you will be asked to enter the
new CRS.

Hallo to all,
do you know how I can transform vectorial data from NAD83 (CSRS98) to UTM
wgs84?
do you think if I do with reproject it would be ok?? or what u suggest??
thanks a lot
