Re: [Qgis-developer] [gdal-dev] Fix for QGIS 2.2+ Projection issue with OSGB36 NTv2
Marco, I think that is a great idea to ship GSB files with QGIS. If the developers of GDAL were to make a decision to bundle them then QGIS should just make use of them. We often encounter datasets in older datums/adjustments and need to use these files. Thanks, Bob Bruce From: qgis-developer-boun...@lists.osgeo.org [mailto:qgis-developer-boun...@lists.osgeo.org] On Behalf Of Marco Hugentobler Sent: March-14-14 8:45 AM Cc: qgis-developer Subject: Re: [Qgis-developer] [gdal-dev] Fix for QGIS 2.2+ Projection issue with OSGB36 NTv2 Hi The info for OSGB36 NTv2 is in srs.db now. 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). I'm receiving frequent suggestions of bundling .gsb files with QGIS. The problems I see with this are: - It adds the extra MB for QGIS too. - They come with various licences. - .gsb files are usefull for all tools working with proj. So a logical choice would be to have an optional package for proj4.

So a logical choice would be to have an optional package for proj4. Yes, but that would be up to others not QGIS, so adding them to the QGIS packages would have more chances of actually happening. It would be nice to have a point of view from those responsible for packaging QGIS. cheers, Etienne Regards, Marco On 13.03.2014 18:20, Etienne Tourigny wrote: On Thu, Mar 13, 2014 at 4:27 AM, Marco Hugentobler marco.hugentob...@sourcepole.ch wrote: Hi I'm adding the entries for OSGB36 NTv2 to srs.db.
