This function returns true if a trajectory object and the specified geometry object intersect in space within the specified time range.
Syntax
boolean ST_intersects(trajectory traj, tsrange range, geometry g);
boolean ST_intersects(trajectory traj, timestamp t1, timestamp t2, geometry g);Parameters
Parameter | Description |
traj | The trajectory object. |
t1 | The start time. |
t2 | The end time. |
range | The time range. |
g | The specified geometry object. |
Example
Select ST_intersects(traj, '2010-1-1 13:00:00', '2010-1-1 14:00:00', 'LINESTRING(0 0, 5 5, 9 9)'::geometry) from traj_table;
