Hi all,
This is an extension of the question I had posted previously regarding
seeing only one point on the map. I had taken example1-1.map from the
tutorial and modified it to display my shapefile. However I was seeing
only one tree when I should have been seeing a whole bunch. Thanks to
David I was able to fix that (I needed to set MINSCALE, athough I don't
know why yet?) and could see the whole set of trees.
Now I have converted that mapfile to serve as a WMS service by adding the
appropriate wms tags in the mapfile. I am getting the capabilites back
correctly. However when I use the OGIS GetMap request I again see just one
tree.
http://pune/mapserver/mapserv.exe?map=/MSTutorial/testwms.map&request=getmap&version=1.1
However if I view the same file i.e testwms.map using the regular
mapserver interface i.e using the command
http://pune/mapserver/mapserv.exe?map=/MSTutorial/testwms.map&mode=map
I see the whole set again. So basically I see just one tree if I give the
OGIS getmap url and a whole set of trees when I give the regular
mapserver url. Any one encountered similar problems or any idea why this
is happening
Here is my map file
