I'm receiving frequent suggestions of bundling .gsb files with
QGIS. The problems I see with this are:<br>

<div>Hi<br>
<br>
I'm adding the entries for OSGB36 NTv2 to srs.db.<br>
For the .gsb file, you could probably contact the
proj4 project if they want it to distribute it
togethere with the library (if the license allows
that).<br>

<div>I guess that's unlikely they would add it to the binary
packages, as it would add a few MB to the base install.
But they might add it to proj-datumgrid-1.5.zip (which
contains many free datum files), as the licence for the
grid is BSD.</div>

<div>Makes me think - could QGIS ship with the freely
available gsb grids, in an optional package (say
qgis-datum-grids)? It would be rather convenient,
especially as QGIS now supports them (but does not ship
with any grids yet, unless mistaken).</div>

<div dir="ltr">Hi all,<br>
<br>
I'm trying to get my fix for the OSGB36
to WGS84 using Ordnance Surveys OSTN02
(NTv2) transformation into the QGIS
master. Nathan Woodrow recommended I
bring it up with you guys who might be
able to implement it. <br>
<br>
Essentially I've updated the QGIS srs.db
and put the OSTN02_NTv2.gsb in the
Share/Proj folder, full description and
files are here: <a href="http://dragons8mycat.wordpress.com/2014/03/03/gis-tips-getting-ostn02-to-work-with-qgis-2-2/" target="_blank">http://dragons8mycat.wordpress.com/2014/03/03/gis-tips-getting-ostn02-to-work-with-qgis-2-2/</a>
<br>
<br>
Is this something which can be
implemented by yourselves or can you
point me in the right direction for
getting it put in the master/future
releases?<br>
<br>
Thanks,<br>
<br>
Nick D (@dragons8mycat)<br>
