[Mapserver-users] How to link maps with different scales

[Bart van den Eijnden]

Hi Johan,

you should make your layers scale dependent in the map file and then GROUP 
them. Put them all in one mapfile.

For scale dependency you use MINSCALE and MAXSCALE.

To group layers together use GROUP "group_name".

See for more elaborate info:

Best regards,
Bart
