[Mapserver-users] help! newbie's question about displaying the shape file.

[shiming]

Hello, everyone,

Recently I installed the MapServer program, and I can run the demo itasca.
I can display shape file from ArcView example in MapServer , but when I 
run with my shape file, there are no image in the image area, just white 
space, but the legend and the reference are showed.
My shape file can be displayed in the ArcView environment.
Is there some requirement about the shape file?
The unit of extent is geographic.

What's wrong with me? Can you point the error for me?
Any ideas will be appreciated.

Thanks in advance.


I use MapServer version 4.0.2 OUTPUT=PNG OUTPUT=JPEG OUTPUT=WBMP 
SUPPORTS=PROJ SUPPORTS=FREETYPE SUPPORTS=WMS_SERVER SUPPORTS=WMS_CLIENT 
SUPPORTS=WFS_SERVER SUPPORTS=WFS_CLIENT INPUT=EPPL7 INPUT=JPEG 
INPUT=POSTGIS INPUT=OGR INPUT=GDAL INPUT=SHAPEFILE

SuSE linux 8.2 and apache2, the directory of 
/usr/local/apache2/htdocs/tmp can be written.
