[ka-Map-users] Is there any way to show a lot of moving gps?

[Paul Spencer]

Hi,

there are some interesting options to have tiles generated without  
caching using meta-data in the map file to control which layers are  
cached and which are not (allowing you to have base layers that are  
cached and a gps layer that isn't).

You can find details in the wiki:

Setting_metadata_in_the_mapfile

In addition, you will likely want to do some custom coding to refresh  
the layer periodically.

Cheers

Paul
