I have map images of my local ward (Areas geo-referenced and drawn using QGIS and Adobe illustrator. Now these maps are in .png format (Raster images). It's not a tile linked to some mapserver such as OSM or Google Maps, but plain vector images which have routes "drawn" out.
I want to be able to link these routes to independent pages (Each route has a set of data stored in a mysql db). I want people to be able to hover over these routes on the vector image with a highlight effect for the route (routes can be curved or straight). And when they click on a particular route, it opens a popup which gives details about the route pulled from the db.
I understand that the PHP GD library can be used for this purpose, but how do i highlight/link routes using this library? If anyone can point me to specific functions from this library, that would help.
Help would be greatly appreciated.
