nothing shows up! no image or error?

Wed Jul 5 11:49:18 PDT 2006

, Hi,

 I am still having problems with not seeing anything. Is this what my code should look like?
LAYER
    NAME "Richland"
    STATUS default
    TYPE polygon
    DATA "RICH_bndy"
    PROJECTION 
     "init=epsg:26914"
    END
    CLASS
      STYLE
            COLOR 0 0 0
      END
  END
END
END

 I also change my entext too.  

Thanks,
Albert

 Projection in MapServer isn't handled with an external  file, like in ArcMap.   It is done in the map file.  Take a look  at the Mapfile documentation to see how to do  projection. 

 http://mapserver.gis.umn.edu/docs/reference/mapfile/projection/view

 You  need to define a projection block in the MAP block of the map file, this is set  to the projection that you want your data output in.  

 You  would then define a projection block in each layer, this is set to the  projection that the original data for that layer is in.  It is easiest to  use epsg codes, look at example 2 in the link above.  

 The  epsg code for UTM zone 14N nad83 is 26914  and 4326 can be used for you  lat/long data.

 David.

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
