distance between a point and a geographical feature

[Miguel Gonçalves]

Hello,

I am using MapServer 4.6 with shapefiles.
I want to know if exists a way of calculating the distance between a 
given point and a geographical feature of my map.
In my case, I have the lines layer "roads" in my map object.
Havin a point (x,y) I want to know the distance to a particular road.
Is there a way of doing it with MapServer?
Thanks.
Best regards.


Miguel
