Número de geometrías rígidas temporales solapadas en cada instante, equivalente a tCount sobre la tpose subyacente

tCount(trgeometry) → tint

SELECT tCount(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]');
-- {[1@2001-01-01, 1@2001-01-02]}

Caja delimitadora agregada de una columna de geometrías rígidas temporales

extent(trgeometry) → stbox

SELECT extent(temp) FROM tbl_trgeometry;

Combinar dos trgeometries con la misma geometría de referencia en un único conjunto de secuencias

merge(trgeometry, trgeometry) → trgeometry
mergeAgg(trgeometry) → trgeometry

SELECT asText(merge(
  trgeometry 'Polygon((0 0,1 0,1 1,0 1,0 0));[Pose(Point(0 0), 0.0)@2001-01-01,
  Pose(Point(5 0), 0.0)@2001-01-02]',
  trgeometry 'Polygon((0 0,1 0,1 1,0 1,0 0));[Pose(Point(0 0), 0.0)@2001-01-04,
  Pose(Point(5 0), 0.0)@2001-01-05]'));
