Thematic mapping in MapServer

As per Steve's suggestion, here's a mapfile from the ForestView application
(http://www.ra.dnr.state.mn.us/forestview/) demonstrating the creation of a
number of map themes from a single shapefile. You'll need to drill down fairly
deep into the application to get to a point where this file is actually in use
(to where you've selected a township and forest inventory (CSA) data is
displayed). I suppose the easiest way to get there would be to just type
something like "T63R23W" into the text input box at the upper left of the first
map page.
The first layer of the mapfile handles all queries; the rest are different
visual slices of the same shapefile. Many of the thematic slices are actually
based on a single attribute field (ctype), and are defined using regular
expressions. Other themes are based on different attribute fields (csize, age,
tbr).
Note that this is a mapserv 3.2 application.
Hope this is helpful,
--Ken
