Display a map using Tiger data

[ryan]

Hi,

I'm having trouble displaying a map of street data i got from the tiger LINE
project.  mapserv doesn't give me any errors, just shows a blank png.  I can
run the demo stuff fine.  I've also tried changing STATUS from ON to OFF to
DEFAULT in my mapfile.  Also, I don't know for sure what the extent of my
map should be, but i'm passing 1.00, 1.00, 50000.00, 50000.00 because i can
use arcexplorer on my windows machine to find that the dimensions of the map
are about 50Km by 50Km.

Here is the web address i access:
http://localhost/cgi-bin/mapserv?map=/usr/bin/apache/htdocs/mapserver/simple.map&mode=map&layer=Freeways&mapext=1.00%201.00%2050000.00%2050000.00&imgsize=300%20300

And my map file is here:

#-------start of map file---------------#
NAME sampleMapServer
# the below extents and size are provided in the URL and so must be removed
#EXTENT 482925.85 3625874.39 497393.16 3617143.43
#SIZE 300 300
SHAPEPATH "data"
UNITS meters

#all layers default to off.
# Note that the layers are drawn depending on their order in this file, from
top to bottom, and

LAYER
  NAME Freeways
  TYPE LINE
  DATA tgr49035lkA
  STATUS DEFAULT
   CLASS
    COLOR 255 0 0
  END # end of class object

END # end of layer object
END # end of map file
#-------end of map file---------------#

I've also put my shapefiles online if anyone would care to look at them:

This is a SuSE linux machine.  mapserver was compiled with the following
configure command:

./configure --with-postgis --with-jpeg=/usr/bin/jpeg
--prefix=/usr/bin/mapserver --with-httpd=/usr/bin/apache/bin/httpd
--with-proj=/usr/bin/proj4


Thanks for any help.  I've been banging my head against my desk and
searching through all the documentation for a few days now.  I really
appreciate anything you could throw my way.
