Mapserver and Tiger:Difficulty Generating Images roguewraith 07-11-2006

 I starting to learn how to use GIS for a school project and I am having
difficulty getting mapserver to generate images from Tiger data files.
All I get in the end is a blank image of nothing.

Any pointers to websites that have more details or examples than the
mapserver site would be appreciated.

Here is my map file for reference

MAP
STATUS ON
SIZE 800 500
IMAGETYPE GIF
IMAGECOLOR 240 240 240
        EXTENT -1000 -1000 1000 1000
        WEB
                IMAGEPATH "C:/ms4w/Apache/htdocs/test/tmp/"
                IMAGEURL "/test/tmp/"
        END


        LAYER
                DEBUG ON
                NAME Complete_Chain
                TYPE LINE
                STATUS ON
                CONNECTIONTYPE OGR
                CONNECTION "C:\ms4w\Apache\htdocs\test\data\TGR220701,0"
                CLASS

                        END
                END
        END # Layer 1

 I figured out my mistake. I had incorrect values for my extent, but
everything else was correct. See the following mailing list link for
how to grab the extent data.
