[Mapserver-users] WMS help

[Lowther, David W]

Ryan,

Thanks for your help. And, you're right. I got it to work just fine. 

Except when I try to project.

The working version of my mapfile (client) contains:

EXTENT -102 33 -94 37
UNITS DD

and no PROJECTION params.

If I change the mapfile (client) to read:

EXTENT -633771.227805 1060738.573036 152927.340425 1689379.870746 
UNITS METERS
PROJECTION # ALBERS OK -all drg's and doqq's on geo site are OK ALBERS
	proj=aea
	lat_1=29.500000000 #SP1
	lat_2=45.500000000 #SP2
	lat_0=23.000000000 #REF LAT
	lon_0=-96.000000000 #CENTRAL MERIDIAN
	x_0=0.000 #FALSE EAST
	y_0=0.000 # FALSE NORTH
	datum=NAD83
	ellps=GRS80
	no_defs
END

The maps generate just fine for all non-wms layers with the second set of
settings. As soon as I turn on a WMS layer the browser just waits and waits
while mapserv.exe is running on the client web server. The exe is hung. So
it seems to be something with the projections... Would you agree? Ideas?

Dave

Hey Dave,

Well, I just added your layer (with some alterations) to my own mapfile, and
it came in just fine. The layer definition I used was:

LAYER 
  NAME cnty_wms
  STATUS ON
  TYPE line
  CONNECTIONTYPE WMS
  CONNECTION
"http://geo.ou.edu/cgi-bin/mapserv.exe?map=wms.map&VERSION=1.1.0&LAYERS=Coun
ties&FORMAT=image/png&TRANSPARENT=TRUE"
  PROJECTION #GEOGRAPHIC NAD83
    proj=longlat
    ellps=GRS80 
    no_defs 
  END
  METADATA
    "wms_title" "County" 
    "wms_srs"   "EPSG:4269 EPSG:4326"
    "wms_connectiontimeout" "10"
  END
END

Just thought you'd like to know..

Ryan

Howdy List,

I am trying to setup WMS Server and Client stuff. The files in the doc are
great. I've setup the server, tested XML output, and run it through
cubeview. Evertyhing looks good.

http://geo.ou.edu/cgi-bin/mapserv.exe?map=wms.map&REQUEST=GETCAPABILITIES

http://geo.ou.edu/cgi-bin/mapserv.exe?map=wms.map&VERSION=1.1.0&REQUEST=GETM
AP

Problem is I can't get the client cooking from here.

Here's the layer def from the client mapfile:
LAYER 
	GROUP "Administrative Boundaries"
	NAME cnty_wms
	TYPE LINE
	STATUS OFF
	CONNECTIONTYPE WMS
    CONNECTION
"http://geo.ou.edu/cgi-bin/mapserv.exe?map=wms.map&VERSION=1.1.0&LAYERS=Coun
ties&FORMAT=image/png"
#	DATA county
	PROJECTION #GEOGRAPHIC NAD83
		proj=longlat
		ellps=GRS80 
		no_defs 
	END
	METADATA
		"wms_srs"   "EPSG:4269 EPSG:4326"
		"wms_connectiontimeout" "10"
		legend_order "140"
 	END
	CLASS#
		MAXSCALE 100000
		SYMBOL "line"
	    COLOR 98 98 98
    	SIZE 8
	END
	CLASS#
		MINSCALE 100001
		SYMBOL "line"
		NAME "County Boundary (WMS)"
    	COLOR 98 98 98
		SIZE 2
	END
END

Anybody got any idea what I'm doing wrong here? I don't really understand
the relationship between the server mapfile projection, server layer
projection, client mapfile projection, and client layer projection. Could
this be causing my problems? Can anyone else see this layer?

Thanks for any help,
