[mapserver-users] Reference map solved, now choropleths

[Doug Nebert]

Thanks to the comments I was able to make the reference map appear
by itself with a GET-based rectangle imposed in the return. Looks 
great.

1. I was wondering recently about the ability and options for creating
choropleth maps via mapserver. These would be the application of,
say, a color ramp or set of many colors to values in a selected 
field and display the polygons (or lines, or points!) in different
colors based on the user request. These would not be static colors
but selected by the user via GUI.

What would be needed to pull this off? A dynamic map file? Special
color palette? 

2. Is there any geocoding support within a mapserver application 
yet? Shapefiles can host attributes which define address ranges and
direction on lines. Has anybody yet built a free parsing routine to 
create a points (event) layer based on a file of many addresses, or
must ArcView be used for this? The obvious follow-on would be a 
routing application along networks. 

Checking the envelope...
