<p>Neil,</p>
<p>There's no support for SRS handling (both in reading or writing)
in the GDAL GS7BG driver:
<a class="moz-txt-link-freetext" href="https://github.com/OSGeo/gdal/blob/master/frmts/gsg/gs7bgdataset.cpp">https://github.com/OSGeo/gdal/blob/master/frmts/gsg/gs7bgdataset.cpp</a></p>
<p>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.</p>
<p>Can you share sample datasets of grids created by Surfer with a
CRS assigned to them?<br>
</p>
<p>Even<br>

<div>Hi,</div>
<div><br>
</div>
<div>I have been trying to save a CRS to Surfer 7 grid files for
distribution to other users. If I assign the CRS (EPSG 26912)
to the grid in Surfer, it is recognized by Surfer. If I
assign it within a QGIS (3.34) project everything works well.
But if I try to assign the CRS within QGIS either through
Assign Projection or Exporting the file, the CRS isn't
recognized by ARC GIS or QGIS.</div>
<div><br>
</div>
<div>Am I missing a step or is there a bug or something?</div>
