We faced two options when we developed our online map: Go with the AJAX
technology (although when we started planning it, I don't think google
maps was not even around!), or go with Java applet technology. It seems
that we are the only NZ Java applet based map around. Whether it was
the right decision or not remains to be seen, but the main advantages
that pushed us in the Java Applet technology direction were:<br>
<br>
1) very small packet sizes. Once the map is loaded, each "view" is
around 10-15kb of vector info (as opposed to a bitmap image of the map)
or less which makes for an instantaneous update, even on dial-up it's
fast.<br>
2) use vector on the servers. Makes it easy to update layers
independantly and keeps the server requirements quite low. We can
handle rather a lot of traffic quite easily with a minimum of servers.<br>
3) Freedom to design the interaction (ie navigation) however we wanted.
Animated zooming, intuitive mouse interaction on both the map and the
overview.<br>
4) The possibility of reusing the Java applet code for other uses later
on (eg, mobile phones, cross platform thin client).<br>
5) easy to add 3rd party layers.<br>
<br>
Of course there are some downsides too, but as I said, it remains to be
seen if we made the right choice.<br>

We are overhauling the whole TUMONZ interface for version 3 and using
the mapplet navigation style. One thing we have realised as TUMONZ 2
has grown - it has become difficult to use cause we just added stuff to
it all the time. We are spending a lot of time on getting the GUI right
this time so if you want to be part of the beta program, any feedback
you can provide will be welcome.</div>
