[Qgis-user] Saving CRS to Surfer 7 grd file

[Even Rouault]

Neil,

There's no support for SRS handling (both in reading or writing) in the 
GDAL GS7BG driver: 
https://github.com/OSGeo/gdal/blob/master/frmts/gsg/gs7bgdataset.cpp

Missing feature likely. Nobody has significantly touched this driver in 
the last 17 years since it was initially contributed. We were even 
considering removing the write side as there was no evidence it was used 
at all.

Can you share sample datasets of grids created by Surfer with a CRS 
assigned to them?
