[mapserver-users] SVG

[Stephen Lime]

Actually MapServer is having GML output added as we speak. Initially this will be available
via the OpenGIS WMT interface but logically it could be added as query output as well. Since
you're talking raw data here it boils down to queries rather than full draws. I believe there are tools
to move from GML to SVG but haven't played in that area at all.

This GML addition is really the last addition before the official 3.5 release, so soon...

I find a Perl SVG library at http://cs.nott.ac.uk/~jxm/SVG/iexplore.html, maybe useful for this thread.
