Another WMS Problem Thread

NeilMartinko

I'm trying to add my own MWS layer to the precompiled Flex Viewer 2.5. I can some Iowa State weather WMS layers to work, but I can't get my own.

This URL brings up an image of the County...
-- http://69.179.87.74:8888/cgi-bin/mapserv.exe?map=C:/Projects/county_sphmerc.map&service=WMS&mode=MAP&layer=COUNTY

This is the URL of the Flex Viewer app...
-- http://69.179.87.74/flex

My config.xml is...

<?xml version="1.0" ?> <configuration>     <title>Iron County Test</title>     <subtitle>a test web mapping application</subtitle>     <logo>assets/images/logo.png</logo>     <style>         <colors>0xFFFFFF,0x333333,0x101010,0x000000,0xFFD700</colors>         <alpha>0.8</alpha>     </style>     <!-- replace the following url with your own geometryservice -->     <geometryservice url="http://tasks.arcgisonline.com/ArcGIS/rest/services/Geometry/GeometryServer" />  <!--splashpage label="ArcGIS Viewer for Flex" config="widgets/Splash/SplashWidget--ironcounty.xml" url="widgets/Splash/SplashWidget.swf"/-->     <!-- UI elements -->     <widget left="10"  top="50"    config="widgets/Navigation/NavigationWidget.xml" url="widgets/Navigation/NavigationWidget.swf"/>     <widget right="-2" bottom="-2" config="widgets/OverviewMap/OverviewMapWidget.xml" url="widgets/OverviewMap/OverviewMapWidget.swf"/>     <widget right="20" top="55"    config="widgets/MapSwitcher/MapSwitcherWidget.xml" url="widgets/MapSwitcher/MapSwitcherWidget.swf"/>     <widget left="0"   top="0"     config="widgets/HeaderController/HeaderControllerWidget.xml" url="widgets/HeaderController/HeaderControllerWidget.swf"/>   <map wraparound180="false" initialextent="-10081233 5776361 -10009752 5876400" top="30">   <basemaps>             <layer label="Streets" type="tiled" visible="flase" url="http://server.arcgisonline.com/ArcGIS/rest/services/World_Street_Map/MapServer"/>             <layer label="Aerial" type="tiled" visible="false" url="http://server.arcgisonline.com/ArcGIS/rest/services/World_Imagery/MapServer"/>             <layer label="Topo" type="tiled" visible="true"  url="http://server.arcgisonline.com/ArcGIS/rest/services/World_Topo_Map/MapServer"/>   </basemaps>         <operationallayers>    <layer label="NEXRAD"                                    type="wms" skipgetcapabilities="true"                                    url="http://mesonet.agron.iastate.edu/cgi-bin/wms/nexrad/n0q.cgi"                                    version="1.1.1"                                    visible="false"                                    visiblelayers="nexrad-n0q-900913"                                    alpha=".5" />    <layer label="NWS WARNINGS"                                    type="wms"                                    skipgetcapabilities="true"                                    url="http://mesonet.agron.iastate.edu/cgi-bin/wms/us/wwa.cgi"                                    version="1.1.1"                                    visible="false"                                    visiblelayers="nexrad-n0q-900913" />    <layer label="IRON COUNTY"                                    type="wms"                                   skipgetcapabilities="true"                                    url="http://69.179.87.74:8888/cgi-bin/mapserv.exe?map=C:/Projects/county_sphmerc.map"                                    version="1.1.1"                                    visible="true"                                    visiblelayers="COUNTY" />         </operationallayers>     </map> </configuration>

The map works fine, and the weather layers appear fine, but the County boundary is missing. Can anybody else see why?

Thanks.

Neil,

Your issue is common to most all issues with WMS service usage in Flex Viewer. Your service supports EPSG:900913 and DOES NOT support EPSG: 102100 or EPSG: 3857 With are Web Mercator and the Projection that your map is in. WMS services do not re-project on the fly.

You need to make sure your WMS service supports EPSG: 102100 or EPSG: 3857

You can also set the wkid attribute on the layer tag if the wms layer supports an equivalent wkid to the map's spatial reference.

See:

OK. Changing the WMS config to EPSG: 3857 makes it work. 900913 has the exact same specs... It must be like somebody asking for two cups and somebody else saying, "Sorry, I don't have any. All I have are pints."

Thanks, Robert!
