Vector data smoothing and palettes

[Dan Taylor]

Hi,

I'm pretty new to mapserver, but I think I'm making reasonable
progress.  Have managed to get my head around the vmap0 and gtopo30
datasets to generate some good results.  However, I am having problems
displaying raster data nicely when zoomed in.

Basically, the problem is with jagged edges.  I've created about 20
classes in my map file with a range of different colours to display
the gtopo30 data, but I still get very jagged edges - especially in
mountainous areas like the Himalayas or the Rockies.

Is there a more elegant way to display raster data than using a huge
set of classes?

Can anyone suggest good classes/colours/palette to use with gtop030?

Is there some way of smoothing the height data to avoid jagged edges?

Cheers,

Dan
