[ka-Map-users] basic Q: creating a map on the fly

[Paul Spencer]

John,

this is actually not that easy to do.  ka-Map is optimal when used  
with base data that doesn't change and feature overlays (primarily  
points).

That being said, a bunch of work was done to enable layers to be  
rendered from dynamic data.  You can approach it in one of two ways:

1) modify tile.php so that it can create your dynamic layers on the  
fly when the appropriate tile is requested

2) use "no_cache" metadata and pass variables for substitution into  
an existing layer

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

Cheers

Paul
