    <p>Hi,</p>
    <p>I second Even argument and I would prefer to change QGIS
      implementation. It does not make sense to have QGIS WKT strings
      not compatible with other Python tools (based on GEOS/JTS, like
      shapely, for example) and ogr.</p>
    <p>>>> import shapely<br>
      >>> shapely.to_wkt(shapely.Point(0, 0, 0))<br>
      'POINT Z (0 0 0)'<br>
      >>> shapely.from_wkt('POINT Z (0 0 0)')<br>
      <POINT Z (0 0 0)><br>
      <br>
    </p>
    <p>Regards,</p>
    <p>Jorge  Gustavo<br>

      <p>Are they? I may have missed something in the Simple Features
        spec, but looking at <a class="moz-txt-link-freetext" href="https://portal.ogc.org/files/?artifact_id=25355" moz-do-not-send="true">https://portal.ogc.org/files/?artifact_id=25355</a>
        , I can't see where it would allow the form {geometryTypeName}Z
        without a space between {geometryTypeName} and Z. <br>
      </p>
      <p>For example the BNF at page 56 shows:</p>
      <p><point z tagged text> ::= point z <point z text></p>
      <p>The examples at page 62 also show a space.<br>
      </p>
      <p>Even<br>
