    <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 href="https://github.com/OSGeo/gdal/commit/1d2e7bc8fcde059de853335fee390479d457be06" target="_blank">https://github.com/OSGeo/gdal/commit/1d2e7bc8fcde059de853335fee390479d457be06</a></p>
    <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 href="https://github.com/OSGeo/gdal/issues" target="_blank">https://github.com/OSGeo/gdal/issues</a> 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>Using conda installed GDAL 3.2.1</div>

        </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>

        <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>
