[mapserver-users] HTML Legends - What Good Are They?

[Chris Garrard]

Bill,

I have some apps that use HTML legends and custom metadata variables.  See
http://earth.gis.usu.edu/utah/advanced.phtml for one.  The groups of data
are collapsible, and I also use metadata to figure out which ones should
have legends shown in the TOC, which ones should have links to legends, etc
(at least I think that's how I did that -- it was a while ago and I'm too
lazy at the moment to go hunt down the files).  If you're interested, I'll
take the time to find some sample files for you.
