I'll probably only be talking about the GIS system if any of the other 
presenters fail to show up, otherwise my talk will happen next month 
alongside James Holden's AJAX talk.

Whether it's next Monday or next Month, I'll be talking about a GIS system 
we've developed for the Yorkshire and Humberside Regional Broadband 
Consortium (YHGfL) for use by all the schools in the region. It's hosted on 
GNU/Linux systems and uses Apache, PHP and MySQL at the server end and a 
combination of XHTML, Java and Javascript at the client end.

The aim was to produce a cross platform (and eGIF compliant) tool which would 
allow pupils and teachers to:
view Ordnance Survery mapping data (both raster and vector)
view overhead photography
view and search gazetteer information (e.g. Ordnance Survey AddressPoint)
measure distances and areas
draw stuff on the maps
add their own geo-referenced information to the system

Along the way we've had to deal with some pretty large data sets, to coax the 
database into handling large numbers of fairly hairy queries and make the 
system play well with all the proxy caches between it and the users.
