nothing shows up! no image or error?

Wed Jul 5 09:58:25 PDT 2006

Hi,

 I was using a projection file UTM Zone 14n Nad_83. Then I switch to an unprojective file and I saw my data show up.  What would be the first best step for setting a projection file?

Thanks
Albert

 Do you  really intend to show a primarily empty stretch of the northern Atlantic Ocean  (apologies to Canary Islanders...)?  

 You  are telling MapServer that your map area is contained within a box from 50 deg.  west longitude to 10 deg. west longitude and 20 to 90 degrees north  latitude.  If the name of your mapfile relates to the data, I am guessing  that Richland County isn't in this box.  

 Use  ogrinfo or a desktop GIS app to look at the extent of your data.  Also, the  extent needs to be in the units of the spatial reference system that your data  is in.  

 David.

Hi,

 I am making    my own map file.  It looks all right but when I click the button it    doesnt show an image or any kind of errors.  

Here is my map    code.
#This is Richland County Map Server
NAME "Richland"
SIZE 100    100
IMAGECOLOR 255 255 255
IMAGETYPE JPEG
SHAPEPATH    "/home/mapdata/"
EXTENT -50.00 20.00 -10.00 90.00
WEB
  TEMPLATE    '/var/www/htdocs/richland.html'
  IMAGEPATH    '/var/www/htdocs/tmp'
  IMAGEURL    '/tmp/'
END
LAYER
    NAME    "Richland"
    STATUS default
    TYPE    polygon
    DATA "RICH_bndy"
       CLASS
          STYLE
                  COLOR 0 0 0
       END
       END
END
END

here is my html    code
<html>
<head><title>Richland County    MapServer</title></head>
<body>
  <form    method=post action="/cgi-bin/mapserv">
    <input    type="submit" value="Click Me"
    <input type="hidden"    name="map"
                 value="/home/mapdata/richland.map">
    <input    type="hidden"    name="map_web_imagepath"
                 value="/var/www/htdocs/tmp/">

  </form>
     <table border="1" width="400" height="400">
     <tr>
  <td align="center" valign="top">
  <IMG    SRC="[img]" width="400" height="400" border="1">
     </td>
  </tr>
     </table>
</body>
</html>

 I really dont    know whats could be wrong.  Maybe the extent of it?  Can anyone help    me?

Thanks,
Albert
