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

You may want to take a look at your extent.

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.

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="">
    <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="" 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
