Clickable Rotated Floorplans on the Web

[Kyle Mulka]

Hello,

So... I want to georeference a bunch of floor plans... got that down, 
not a problem. Then, I want to serve them on the web via the Google Maps 
interface... again not a problem. The problem come in when I want north 
to be another direction besides straight up. I can no longer use Google 
Maps, because I can't figure out how to get it to rotate its coordinate 
system so that I can add markers via lat/long and detect the lat/long of 
a point the user clicks on.

The other problem I'm having with mapserver is that the images it 
creates are not as clean as the original input image. Here's with mapserver:

Here's without:
http://maps.kylemulka.com/imagemagick/liveugli.php

Notice how much clearer the second set of maps are when I don't use 
mapserver. I'm instead simply using imagemagick to tile the input image. 
You may have to zoom in all the way to see the difference. Also notice 
that north has to be straight up when I try to place markers by lat/long.

What are the possible solutions to these two problems? Does anyone know 
of software I could to help me out here? I don't want to use Flash or a 
Java Applet because of the need to install plugins.

Thanks,
