Maps is a simple php script that highlights areas, adds labels, and draws paths on images. I don't have time to document it as it was a quick hack to get a map display web page working for CSUS.
You can download the code which you might be able to understand (or might not - it was my first php script).
There might be a working version running on the CSUS maps page if the School hasn't destroyed the CSUS server again or CSUS hasn't broken it yet again.
