[pgrouting-dev] Driving Distance Help

[Stephen Woodbridge]

Hi all,

Since I wrote my own driving distance code years ago and have been happy 
with it, I have just now looked into how the pgRouting code works.

Does this code return multiple contours in a single request? How?

It looks like this code can only return a single contour for a single 
request. This means if I want say contours for 5, 10, 15 minutes that I 
have to make 3 requests which means fetching the data, building the 
graph and creating the contours all have to be processed 3 times. It 
seem that it would make more sense to setup the problem once and compute 
all the contours at once and return 3 results.

Thoughts?
