<p><font face="monospace">Hi,</font></p>
<p><font face="monospace">Geospatial data conflation is not an easy
task, and usually depends on : <br>
</font></p>
<p><font face="monospace">- the input data</font></p>
<p><font face="monospace">- desired output</font></p>
<p><font face="monospace">- semantics</font></p>
<p><font face="monospace">- conflation based mainly on semantics( /
attribute data ), topology or purely geometric</font></p>
<p><font face="monospace">Note that semantic and topology-based
methods are much more robusts than geometry-based ones.<br>
</font></p>
<p><font face="monospace">In any case, there is no magic workflow
and the method has to be adapted to the specific context.</font></p>
<p><font face="monospace">I contributed to an implementation based
on PostGIS quite a long time ago : <br>
</font></p>
<p><font face="monospace"><a class="moz-txt-link-freetext" href="https://docplayer.fr/8718145-Appariement-de-graphes-de-reseau-avec-postgis.html">https://docplayer.fr/8718145-Appariement-de-graphes-de-reseau-avec-postgis.html</a>
( in french ).<br>
</font></p>
<p><font face="monospace">There could be some generic algorithms
which could be made available in QGIS processing to ease
creation of workflows for conflation ( e.g. node fingerprints,
geometry local correspondance search ).<br>
</font></p>
<p><font face="monospace">Get in touch if you are interested in
developing some.</font></p>

a lack of conflation tools in QGIS like such existing for Esri
