[ka-Map-users] Creation of layer as per user's query.

[Paul Spencer]

There is some information on drawing dynamic tiles in the ka-Map wiki:

http://ka-map.ominiverdi.org/wiki/index.php/ 
Setting_metadata_in_the_mapfile

The alternate approach if you have less than a couple of thousand  
points is to add them as overlays on the client side.  In this  
method, you could make an XmlHttpRequest to the server to retrieve  
the points for the schools and then call myKaMap.addObjectGeo for  
each point.

Cheers

Paul
