Fwd: Re: Timeseries WMS

[Daniel Morissette]

The following mails from the archives talk about generating animated maps:
http://lists.gis.umn.edu/pipermail/mapserver-users/2003-September/007081.html
http://mapserver.gis.umn.edu/data2/wilma/mapserver-users/0108/msg00261.html

A wrapper could be written in MapScript to assemble the animated image 
using whirlgif as suggested in those messages and return it in response 
to WMS GetMap requests.
