thank you for the reply..can you be more detail please..i've tried your
suggestion but it returned no record.
I create a simple illustration below.. the green line is the record from
road table, and the red line is the route table generated from
ST_Makeline(gps_points), I want to make the red line snap into the road so
it become the route
Thank you in advance
