Description

I have executed this query:

SELECT * FROM shortest_path('SELECT gid AS id, source::int4,

target::int4, "LENGTH"::double precision AS cost,"LENGTH"::double precision

AS reverse_cost FROM rd_ksa',306, 359, true, true);

and My out put looks like:

Vertex_id | edge_id | cost


306 + 275 + 61.4456 359 + -1 + 0

My doubt is how will I make use of these lines to draw shortest line in my map. What actually the feild cost indicates.
