Construir una geometría rígida temporal a partir de una geometría de referencia y una pose temporal

trgeometry(geometry, tpose) → trgeometry

SELECT asText(trgeometry(
  geometry 'Polygon((0 0,1 0,1 1,0 1,0 0))',
  tpose 'Pose(Point(0 0), 0.0)@2001-01-01'));
-- POLYGON((0 0,1 0,1 1,0 1,0 0));Pose(POINT(0 0),0)@2001-01-01

Ambos argumentos deben compartir el mismo SRID. La geometría de referencia puede ser un polígono o una superficie poliédrica; la pose puede ser de cualquier subtipo temporal.

Agregar un único instante a una trgeometry existente, ampliando la trayectoria de pose subyacente

appendInstant(trgeometry, trgeometry [, maxdist float [, maxt interval]]) → trgeometry

SELECT appendInstant(
  trgeometry 'Polygon((0 0,1 0,1 1,0 1,0 0));[Pose(Point(0 0), 0.0)@2001-01-01]',
  trgeometry 'Polygon((0 0,1 0,1 1,0 1,0 0));Pose(Point(5 0), 0.0)@2001-01-02');

Agregar una secuencia completa a una trgeometry existente

appendSequence(trgeometry, trgeometry) → trgeometry

SELECT asText(appendSequence(trgeometry 'Polygon((0 0,1 0,1 1,0 1,0 0));
  [Pose(Point(0 0), 0.0)@2001-01-01, Pose(Point(10 0), 0.0)@2001-01-02]',
  trgeometry 'Polygon((0 0,1 0,1 1,0 1,0 0));
  [Pose(Point(20 0), 0.0)@2001-01-03, Pose(Point(30 0), 0.0)@2001-01-04]'));
-- POLYGON((0 0,1 0,1 1,0 1,0 0));
-- {[Pose(POINT(0 0),0)@2001-01-01, Pose(POINT(10 0),0)@2001-01-02],
--   [Pose(POINT(20 0),0)@2001-01-03, Pose(POINT(30 0),0)@2001-01-04]}
