One issue could be that you've asked Mapserver to render the entire world:<div class="im"><br>
<br>
EXTENT -<a href="tel:90%20-180%2090%20180" value="+19018090180" target="_blank">90 -180 90 180</a><br>
<br></div>
into a small image:<br>
<br>
mapsize=600+800<br>
<br>
Adjust the extents of the output image to be the extent of you contour data. I see that you've given that in your LAYER definition<div class="im"><br>
<br>
EXTENT 143 -20 145 -19<br>
<br></div>
so try that for the map extent (but I think it would be valid only if the contours were stored in a Geographic system and not a Projected system). What SRS are you storing your data in? The same as your display (EPSG:4326)?<br>
<br>

Hi,<br>
<br>
I'm trying to get Mapserver connected with PostGIS. PostGIS is holding<br>
a shape2pgsql contourline import in the table "atest" while a test has<br>
the following columns (shape2pgsql default):<br>
<br>
------------------------------<u></u>--------<br>
| Actions | gid | id | height | geom |<br>
------------------------------<u></u>--------<br>
<br>
Quantum GIS picks the conection up perfectly to atest but with<br>
Mapserver I just get a blank screen - or the color of IMAGECOLOR [. .<br>
.] definition in test-2.map definitions.<br>
<br>
Somehow it seems like I got the connection between Mapserver and<br>
PostGIS running - at least the debug.log doesn't complain. But still<br>
I'm not seeing any of my contour lines as I'm used to by Quantum GIS<br>
;(<br>
<br>
Could someone give me a hint of what I'm missing out or where my mistake is?<br>
I got the feeling that it is either has something to do with the DATA<br>
property or the projection properties …<br>
<br>
The Link with which I call the mapserv binary is:<br>
<br>
<a href="http://192.168.10.15/cgi-bin/mapserv?map=./Maps/test.map&mode=map" target="_blank">http://192.168.10.15/cgi-bin/<u></u>mapserv?map=./Maps/test.map&<u></u>mode=map</a><br>
But then it complains:<br>
msDrawMap(): Image handling error. Unable to initialize image.<br>
msPrepareImage(): General error message. Image dimensions not<br>
specified. msCalculateScale(): General error message. Invalid image<br>
width or height.<br>
<br>
So I changed it to the following:<br>
<a href="http://192.168.10.15/cgi-bin/mapserv?map=./Maps/test.map&mode=map&mapsize=600+800" target="_blank">http://192.168.10.15/cgi-bin/<u></u>mapserv?map=./Maps/test.map&<u></u>mode=map&mapsize=600+800</a><br>
which results in no errors but therefore in a blank screen with a<br>
clean debug.log ...<br>
<br>
Even this one wont change anything:<br>
<a href="http://192.168.10.15/cgi-bin/mapserv?map=./Maps/test.map&mode=map&mapsize=600+800&layer=Contour" target="_blank">http://192.168.10.15/cgi-bin/<u></u>mapserv?map=./Maps/test.map&<u></u>mode=map&mapsize=600+800&<u></u>layer=Contour</a><br>
<br>
<br>
. . . my test-2.map definition is below:<br>
<br>
P.S.: TEMPLATE "./Maps/test.map" does exist and is read and writeable<br>
to the user which runs the webserver (Apache => User: www)<br>
CONFIG "PROJ_LIB" "/usr/local/share/proj/" should also be valid:<br>
