Four?! Country; county/unitary authority; borough/district; ...parish/ ward? That's an enormous amount of data: ONS says there are 10661 wards in the UK. While you wouldn't need to draw all of those at once, you would need to store all their boundaries, together with the other datasets. > If the user clients inside one boundary, they are taken to a zoomed in > map of that boundary, with the next stage of regional boundaries. > > When they reach the bottom stage need to extract the geotag to save in > my database. > > I'm a bit of a Maps API noob.

The most fundamental question is: do you have boundary data, and how are you hosting it? The API simply allows you draw lines, it doesn't provide data sets for you. If you have the data, it's just a question of deciding which lines you want to draw and then drawing them. You will need encoded polylines, if not custom tiles, or the client browser will stop working. It's quite an ambitious project. Oh: and you're likely to run into problems with Ordnance Survey licensing.
