<p>Hi,</p>
<p>For posterity: just to note that the below fix turned out to be
incorrect<br>
</p>
<p>See <a class="moz-txt-link-freetext" href="https://github.com/OSGeo/gdal/issues/3605">https://github.com/OSGeo/gdal/issues/3605</a> for more details
and the appropriate fix</p>

<p>Eric,</p>
<p>I believe you're right. I've just fixed the issue by changing
the template resource XML file used by the GDAL driver in</p>
<p><a class="moz-txt-link-freetext"

<p>So you can easily workaround the issue by updating this file in
your existing installation.</p>
<p>For a next time, better file an issue at <a
class="moz-txt-link-freetext"
href="https://github.com/OSGeo/gdal/issues"

however. This will minimize the risk that your report is lost
because nobody was able to address it at the very moment where
they read it.</p>

</div>
<div>Using conda installed GDAL 3.2.1</div>

<div>I think I've stumbled on a bug with the BAG driver. It
seems as though when you use Create() to make a BAG, it
writes the dimensionSize xml attribute in the wrong order.
It sets the column dimension size to the row dimensionSize
xml attribute, and row to column. I found this on examining
the xml manually, see blob below.</div>

</gmd:resolution><br>
</gmd:MD_Dimension><br>
</gmd:axisDimensionProperties></div>
<div><br>
</div>
<div>This bug does not affect viewing the BAG in QGIS, as it
seems like QGIS just computes the size using the actual
array. I found that GDAL created BAGs would not load in
Caris, a software for viewing bathymetric data. I believe
that is because Caris is using the dimensionSize xml instead
of calculating size from the data. If I swap row/col
dimensionSize, the BAG then works in Caris.</div>
<div><br>
</div>
<div>Seems like a relatively simple fix (assuming I am right
about this), please let me know if I need to submit it
somewhere else.</div>
