You can connect to other WMS services such as Demis to display a
world map, either from a server or from a client (using for instance
openlayers)
Demis looks like it could do what I want, in terms of displaying a world
map and so forth, but at 950 EUR, it's beyond my budget at the moment.
I'll poke around for other WMS-like applications, though. Thanks for
the suggestion.
and I'd like to be able to highlight certain airports and draw
different types of lines between them, based on dynamic input from
the user through the Perl application.
You can use user variables to connect to the mapfile (search for
"substitute variables" on the mapserver website. I would like to hand
you the link, but I cannot connect to http://mapserver.gis.umn.edu
at the moment)
Thanks. I'll check this out.
At peak usage, I suspect at least 75 maps would need to be
generated per second, with an average of 30-40 data points and
various amounts of connecting lines between them per map.
Make sure the server is capable of this with regards to bandwidth,
memory and processor capacity. This is in essence not a problem for
mapserv.
I just want to be sure that, with high-end but still commodity hardware,
I'll be able to render enough maps per second to make this worthwhile.
Is this the sort of thing MapServer is good at doing? I've read
some of the web site, and really, I can't make heads or tails of
quite a bit of it, especially with respect to Perl.
I think it is, but it is best to combine it with a strong AJAX viewer
to get the best dynamic user experience and taking the most (views
and queries) out of postGIS.
Indeed. I'd eventually like to implement my maps in Flash on a rotating
globe, but that's down the road a bit for now.
