Re: [Qgis-user] changing .gsb file for transformation

Place the gsb under your "QGIS folder\profiles\default\proj\" and then
select the transformation you want in Settings > Options > CRS > Default
Datum Transformation.

[Qgis-user] changing .gsb file for transformation

2020-02-24 Thread Michael . Dodd
I am trying to use the uk ordnance survey system in qgis along with other data 
in wgs84 and background imagery in other crs.  I have the relevant .gsb files 
for the ostn02 transformation (which currently use instead of the ostn15 
version) but can't see how to persuade qgis to use it instead of one of its 
several less accurate 'ballpark' transformation methods.  How to do this?
