Number of overlapping temporal rigid geometries at each instant, equivalent to tCount on the underlying tpose

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]}

Aggregate bounding box of a column of temporal rigid geometries

extent(trgeometry) → stbox

SELECT extent(temp) FROM tbl_trgeometry;

Combine two trgeometries with the same reference geometry into a single sequence-set

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]'));
