[ms4w-users] isochrons maps with mapserver

[RUIZLUNA jose-carlos]

I am Carlos Ruiz Luna, studying at the School of Engineers of the Canton of Vaud (EIVD) in Switzerland.
I would like to create a website with isochronous charts by using the data bases of TeléAtlas (Shape format).
I installed the OpenSource software MS4W v1.2.2 but i do not have any idea how to create the isochron function by my own in PHP Mapscript. Could you help me?
 
Thanks in advance for your answers, and best regards.
