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.
