Tips for routing with tiger file

[Kurt Kuo]

Dear list,
Here may not be the right place to post this question. However, I understand 
that mapserver users come from different fields. There must be some experts 
who are able to give me some advices. Thanks in advance.
My question is how to use tiger file for routing purpose. As my 
understanding, routing needs the length of every line between source and 
target nodes. It seems that the tiger file does not have this information. I 
really appreciate if someone can provide some advices, tips, or references 
in order to achieve this matter. Thanks again.


Best,

Kurt
