<DIV><FONT face=Arial size=2><EM>Please realize that if you use an EXPRESSION to
select features,<BR>MapServer still has to read *every single feature* in the
input files<BR>and test them against your expression. If you try to do
that for the<BR>whole Northeast, MapServer is still being asked to read *every*
road in<BR>those states even if it ends up selecting and drawing only two of
them</EM>.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Yes this makes sense now that you say
this... I could preprocess out a lot of the</FONT></DIV>
<DIV><FONT face=Arial size=2>minor roads, trails, etc but really I do want the
majority of the roads to be present...</FONT></DIV>
<DIV><FONT face=Arial size=2>Just I wanted to be able to show only the major
highways while zoomed out and then</FONT></DIV>
<DIV><FONT face=Arial size=2>start showing lesser roads as I zoomed in
closer. I'm not entirely sure how to </FONT></DIV>
<DIV><FONT face=Arial size=2>do the preprocessing (I had no GIS knowledge
or experience at all before getting involved</FONT></DIV>
<DIV><FONT face=Arial size=2>with mapserver... I've learned a lot but have a
long ways to go). I'll worry about that later</FONT></DIV>
<DIV><FONT face=Arial size=2>though.. now it's on to prepping another server for
mapserver so I can get back to work on this. Thanks for all the
comments and advice.</FONT></DIV>
