[Mobilitydb-users] Query regarding intersection of a temporal point with Z dimension and polygon

[Esteban Zimanyi]

Dear Sharath

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
https://postgis.net/docs/ST_Intersection.html
satisfy your requirements ? If this is the case, then MobilityDB could take
care of the temporal aspects.

Could you please send us an example of a spatial only example that would
help us to understand what you need?

Esteban
