Reduce Detail on Maps?

[Gregory S. Williamson]

Kyle,

Do you mean to reduce the detail in the lines themselves ?

If you are using postgres you could perhaps use the simplify function:

* 0.60 Simplify(geometry, tolerance)
Returns a "simplified" version of the given geometry using
the Douglas-Peuker algorithm. Will actually do something
only with (multi)lines and (multi)polygons but you
can safely call it with any kind of geometry. Since simplification
occurs on a object-by-object basis you can also
feed a GeometryCollection to this function. Note that returned
geometry might loose its simplicity (see IsSimple)

Not sure what other tools could do this ... perhaps the JUMP tool has such functionality as well, and it can work directly with shape files.

HTH,

Is there any way to reduce the detail and smooth out lines. This:
http://mt.kylemulka.com/um.php?map=/ms4w/umbuildings.map&REQUEST=GetMap&SERV
ICE=WMS&VERSION=1.1.1&LAYERS=Buildings&STYLES=&FORMAT=image/png&BGCOLOR=0xFF
FFFF&TRANSPARENT=TRUE&SRS=EPSG:4326&BBOX=-83.7322998046875,42.27934093085314
5,-83.72955322265625,42.28137302193453&WIDTH=256&HEIGHT=256
Just looks ugly with all the detail in it.
