[mapserver-users] multiple tileindex in a layer

[Daniel Morissette]

Please send your replies via the list so that others who know better 
than me about time support can help, and that other users who may have 
similar problems can benefit from the answers when they search the archives.

Back to your last question, at first sight, what you have seems right, 
and already combines the spatial index and time index. If you have 
multiple images listed in your OMTO3ECOLUMNAMOUNTO3IDX layer that fit in 
the requested map view and whose time attribute match the requested 
time, then they should all be displayed.

If that doesn't work for you, then you will have to provide more 
specific details to help us understand the exact problem.
