Description
We have lines in X,Y,Z that have Z storing timestamps of traveling through points.
ST_ClosestPoint drops Z instead of interpolating it. ST_3DClosestPoint measures distance also across the fake time which is not what we would need.
ST_ClosestPoint should return 3D points for 3D inputs.
Note:
See TracTickets
for help on using tickets.
I disagree :) -- that should go in ST_3DClosestPoint.
We standardized on the ST_ dealing 2D and the 3D ones for 3D + more
