MobilityDB Types

MobilityDB defines four template types that act as type constructors over base types. These template types are set, span, spanset, and temporal. Table A.1, “MobilityDB current instantiations of template types” shows the types defined over these template types. Furthermore, MobilityDB defines two bounding box types, namely, tbox and stbox.
