[Qgis-user] vector shp from NAD83 (CSRS98) to UTM WGS84

[Saulteau Don]

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 provincial (cause I'm in British Columbia) the Provincial
Government has their own GSB for distribution, albeit a different and
non-open license (I've asked for it to be switched to open license as
well). I tend to use those, so asking with Provincial agencies/ministries
would be a good bet too.
