<p>Hello QGIS Users,</p>
<p>good morning from Winterwonderland Tirol in Austria!</p>
<p><font color="#008000">GNSS NMEA interpreted as WGS84 in QGIS can
do transformation with gridshift from ETRS89 to MGI, that is
alredy working very good.</font></p>

<p><font color="#ff0000">GNSS NMEA data interpreted as WGS84,
viewing on map is ok, but saving data in MGI (example 31254),
default position_vector Transformation makes 30 cm gap
(parameters are ok, this was before gridshift exists)!</font></p>

<p><b>How can I make gridshift from WGS84 to MGI like ETRS89 to MGI?</b></p>
<p><b>Does somebody know, is verticalshift working in QGIS (similar
to gridshift in X, Y)?</b><br>
