The #MobilityDB team just announced v1.3.0-alpha featuring
New temporal types:
π tgeometry & tgeography that can represent the temporal evolution of any geometry type (polygon, multipoint, etc.)
π temporal circular buffer (tcbuffer)
π temporal pose (tpose) type, storing the evolution of a pose
(point position + orientation)
and more ...
