I don't think you'd quite need anything as complex as GIS for this. In 
the simplest form you'd just need an imagemap and georeferenced map 
files. Georeference information is simple metadata linking the pixel 
coordinates to the real world. It can be internal to the file (as in 
GeoTIFF), or provided externally (such as an ESRI 'World' file).

I've found a sneaky way of getting web-scale map data from the MNR, but 
they're topo maps, so aren't any use for finding street names/locations.
