[ka-Map-users] Tiling for mapserver.

[Paul Spencer]

Hi Ed.

The code that accomplishes this for ka-Map is in tile.php.  Take a  
look, use what you need (or use the whole thing).

You need to set the EXTENTS (not EXTEND) of the map.  You can try  
using the mapserv cgi if you don't want to use mapscript.  You will  
probably want to use the mapserver users mailing list, however.

Some advice on generating tiles ...

1) draw a larger image (by about 10 pixels) than you really need and  
trim away the edges before cutting tiles (mapserver has some nasty  
edge effects)

2) use "labelcache_map_edge_buffer" "-xx" in the metadata of your web  
object in your map file to prevent labels from being drawn too close  
to the edge of a tile

Cheers

Paul
