[UMN_MAPSERVER-USERS] Intersections

[Skweda O'Bomsawin]

An Idea:

        1- Create a point layer from intersections
        2- In the point layer, add two columns corresponding to the name of
the two roads intersecting
        3- Make two drop-down on your web page where your users can select
intersections (correspondig to columns in the point layer table)
        4- Zoom to that point with a buffer in extents to be at a reasonable
scale

As simple as it is I think!

Can someone please give me some idea or a sample on how one would begin to
find an intersection of two lines, streets in my case. Info on finding
intersecting lines with other data besides streets could be helpful as well.
I ultimately want to give a user the option to enter two street names and
then zoom to that intersection.  Any suggestions or examples?

Eric
