WMS DEMO HELP

Fri Nov 3 17:13:33 EST 2006

I have taken the following actions, as suggested below:

1. Set the servername to 204.244.79.27 in WMS configuration.

2. Published the Samples/Sheyboygan/Hydrography layer by right clicking the
properties of the layer in studio, then clicking the Service Properties tab.

3. Entered the bounds (it was already there, I guess because it is a demo)

Putting this URL in the browser causes the server to serve up the layer:

http://204.244.79.27/mapguide/mapagent/mapagent.fcgi?SERVICE=WMS&VERSION=1.0.0&REQUEST=GetMap&srs=EPSG:4326&WIDTH=402&HEIGHT=525&FORMAT=image/gif&TRANSPARENT=TRUE&LAYERS=Samples/Sheboygan/Layers/Hydrography&STYLES=&BBOX=-87.764987,43.691398,-87.695522,43.797520

However, when I use a WMS browser (Gaia), it shows the layers in a list, but
cannot display them.

I notice that there are a lot of fields in, say a Nasa layer that are
missing in our Hydrography layer, for example:

<Layer queryable="0">
      <Name>global_mosaic</Name> 
      <Title>WMS Global Mosaic, pan sharpened</Title>
      <Abstract>
	Release 2 of the WMS Global Mosaic, a seamless mosaic of Landsat7 scenes.
	Spatial resolution is 0.5 second for the pan band, 1 second for the visual
and near-IR bands and 2 second for the thermal bands
	Use this layer to request individual grayscale bands. The default styles
may have gamma, sharpening and saturation filters applied.
	The grayscale styles have no extra processing applied, and will return the
image data as stored on the server.
	The source dataset is part of the NASA Scientific Data Purchase, and
contains scenes acquired in 1999-2003.
        This layer provides pan-sharpened images, where the pan band is used
for the image brightness regardless of the color combination requested.
      </Abstract>
      <LatLonBoundingBox minx="-180" miny="-60" maxx="180" maxy="84"/>
      <MetadataURL type="FGDC">
	<Format>text/xml</Format>
	<OnlineResource xmlns:xlink="http://www.w3.org/1999/xlink"
	  xlink:type="simple"
	  xlink:href="http://onearth.jpl.nasa.gov/WAF/WMS_GMR.xml"
	/>
      </MetadataURL>
      <Style> <Name>pseudo</Name> <Title>(default) Pseudo-color image, pan
sharpened (Uses IR and Visual bands, 542 mapping), gamma 1.5</Title>
</Style>
      <Style> <Name>pseudo_low</Name> <Title>Pseudo-color image, pan
sharpened (Uses IR and Visual bands, 542 mapping)</Title> </Style>
      <Style> <Name>pseudo_bright</Name> <Title>Pseudo-color image (Uses IR
and Visual bands, 542 mapping), gamma 1.5</Title> </Style>
      <Style> <Name>visual</Name> <Title>Real-color image, pan sharpened
(Uses the visual bands, 321 mapping), gamma 1.5</Title> </Style>
      <Style> <Name>visual_low</Name> <Title>Real-color image, pan sharpened
(Uses the visual bands, 321 mapping)</Title> </Style>
      <Style> <Name>visual_bright</Name> <Title>Real-color image (Uses the
visual bands, 321 mapping), gamma 1.5</Title> </Style>
      <ScaleHint min="10" max="10000"/>
      <MinScaleDenominator>20000</MinScaleDenominator>
    </Layer>

Our Hydrography layer says simply:

<Layer queryable="0" cascaded="0" noSubsets="0" opaque="0">
   <Name>Samples/Sheboygan/Layers/Hydrography</Name>
   <Title>Water resources</Title>
   <Abstract>Water resources of Sheboygan, Wisconsin</Abstract>

   <KeywordList>
     <Keyword>water</Keyword>

   </KeywordList>

  <SRS>EPSG:4326</SRS>

    <LatLonBoundingBox minx="-87.74" miny="43.68" maxx="-87.69"
maxy="43.815"/>

  <BoundingBox SRS="EPSG:4326" minx="-87.74" miny="43.68" maxx="-87.69"
maxy="43.815"/>

  </Layer>

Could these missing tags be the problem? If so, how do you get them in the
WMS output?

Thanks
