[mapserver-users] small maps of alaska and hawaii

[Julie Knoll]

We aren't using open layers, its a completely custom written site. It could
definitely be done, but then there would be a lot of processing going on the
background x 3 and I don't think thats practicle.  I also thought about just
physically moving the shapes closer to the US, but theres about 15 layers
that would have to be updated, that still might just be easiest though.  I
was hoping there was maybe someway I could use mapservers querymap feature
to do this, but I guess not?
