<div dir="ltr">Dear Sharath<div><br></div><div>Many thanks for your question. MobilityDB delegates the spatial processing to PostGIS, which in turn delegates geometrical processing to GEOS. Could you please verify that the behavior provided by PostGIS </div><div><a href="https://postgis.net/docs/ST_Intersection.html">https://postgis.net/docs/ST_Intersection.html</a><br></div><div>satisfy your requirements ? If this is the case, then MobilityDB could take care of the temporal aspects. </div><div><br></div><div>Could you please
send us an example of a spatial only example that would help us to understand what you need? </div><div><br></div><div>Esteban</div><div><br clear="all"><div><div dir="ltr" class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><div>------------------------------------------------------------<br>Prof. Esteban Zimanyi<br>Department of Computer & Decision Engineering (CoDE) CP 165/15 <br>Universite Libre de Bruxelles <br>Avenue F.
