[Mapserver-users] MapServer and PostGIS....

[Nick Ton]

Hi Everyone,

I am a newbie to MapServer. I have read the PostGIS information page on
how to connect MapServer to PostGIS. I have used the shp2pgsql function
to dump some data into PostGIS. Everything seems to be ok on the PostGIS
side.

I have created a test map file to see if I can connect to PostGIS. Here is
my map file that is being referenced by my test html page:

-------------------- map file---------------------------------
NAME S3EX3

WEB
	TEMPLATE /home/nton/public_html/tutorial35/geo_test/s3ex3.html
	IMAGEURL "/~nton/public_html/tutorial35/geo_test/"
END

EXTENT -90. -30 20. 90 
SIZE 600 600

LAYER
    CONNECTIONTYPE postgis
    NAME "airports_tbl"
    # Connect to a remote spatial database
    CONNECTION "user=postgres dbname=geo_db host=172.16.3.82"
    # Get the lines from the 'the_geom' column of the 'airports_tbl' table
    DATA "the_geom from airports_tbl"
    STATUS ON
    TYPE LINE
    CLASS
      COLOR 0 0 0      
    END
  END
END # end of map file
-------------------- map file---------------------------------

I had modified one of the tutorial html file to see if I can make it work.
The
html page returns properly but no image shows up in the designated area.
I used "View Source" on the web browser to see where the image is generated
and it seems to generate the .png file name for the image reference like
this:
<input type="image" name="img"
src="/~nton/tutorial35/geo_test/S3EX31054076682716.png" border="0">
But when I try to locate that image on the local directory it's not there.
Has anyone experienced the same problems? Can some one tell me what 
I am doing wrong?

Thanks In Advance,
Nick
