IT is only a matter of parameter order:

ST_within( line, polygon)

ST_Contains(polygon, line)

Subject: [postgis-users] LineString within Polygon

Hi All,

I want to make sure of what I am doing well.

I want to construct a geometry(LineString) from List of Points which represent the Path between Source && Destination Points.

Afterthen, would like to know if the path fully within a polygon.

What is the correct method, ST_within, or ST_Contains ?!!

Thanks in advance
