Campus Map Software?

Hey guys,
This semester my classes are spread out all over the place and are different each day. I was wondering if there was a program that I could drop a pdf or image of my campus map in and put in where I'll be at a certain time and where I have to go. With tabbed days, only showing certain days at a time. Sort of like iCal, but with maps? Or even a program that will pull my Ical events haha because I have my schedule all in iCal.

Any suggestions would be helpful. Thanks!
