WMS getCapabilities and SRS

[Sture Dingsøyr]

Hi

 

I have a question regarding the SRS tag in getCapabilities.

 

In my mapfile I put all the EPSG codes that I want my layers to be available in with the METADATA tag ?wms_srs?, so that my layers look like this:

 

LAYER

            PROJECTION

                        "init=epsg:32633"

            END

            METADATA

                        "wms_title"                                                                    "Fylke flate"

                        "wms_srs"                                                                                 "EPSG:4326 EPSG:25831 EPSG:25832 EPSG:25833 EPSG:25834 EPSG:25835 EPSG:27391 EPSG:27392 EPSG:27393 EPSG:27394 EPSG:27395 EPSG:27396 EPSG:27397 EPSG:27398 EPSG:32631 EPSG:32632 EPSG:32633 EPSG:32634 EPSG:32635 EPSG:102132 EPSG:102133 EPSG:102134 EPSG:102135"

                        "wms_abstract"                                     "For å hente dette tema via WMS må ein nytte layer_74 som verdi i LAYER parameter"

                        "gml_include_items"                  "all"

            END

            DATA "adaptive/74"

            STATUS off

            TRANSPARENCY 50

            TYPE polygon

            DUMP TRUE

            TEMPLATE "TRUE"

            NAME "layer_74"

            CLASS

                        COLOR 0 0 0

                        NAME "Fylke flate"

                        OUTLINECOLOR 255 255 255

                        SYMBOL "horizontal"

            END

END

 

 

In my getCapabilities file all the correct SRS tags are displayed like this:

- <Layer queryable="1" opaque="0" cascaded="0" noSubsets="0">

  <Name>layer_74</Name> 

  <Title>Fylke flate</Title> 

  <Abstract>For å hente dette tema via WMS må ein nytte layer_74 som verdi i LAYER parameter</Abstract> 

  <SRS>EPSG:4326</SRS> 

  <SRS>EPSG:25831</SRS> 

  <SRS>EPSG:25832</SRS> 

  <SRS>EPSG:25833</SRS> 

  <SRS>EPSG:25834</SRS> 

  <SRS>EPSG:25835</SRS> 

  <SRS>EPSG:27391</SRS> 

  <SRS>EPSG:27392</SRS> 

  <SRS>EPSG:27393</SRS> 

  <SRS>EPSG:27394</SRS> 

  <SRS>EPSG:27395</SRS> 

  <SRS>EPSG:27396</SRS> 

  <SRS>EPSG:27397</SRS> 

  <SRS>EPSG:27398</SRS> 

  <SRS>EPSG:32631</SRS> 

  <SRS>EPSG:32632</SRS> 

  <SRS>EPSG:32633</SRS> 

  <SRS>EPSG:32634</SRS> 

  <SRS>EPSG:32635</SRS> 

  <SRS>EPSG:102132</SRS> 

  <SRS>EPSG:102133</SRS> 

  <SRS>EPSG:102134</SRS> 

  <SRS>EPSG:102135</SRS> 

  <LatLonBoundingBox minx="-0.952145" miny="57.7524" maxx="31.9287" maxy="71.5653" /> 

  <BoundingBox SRS="EPSG:32633" minx="-77249.9" miny="6.4483e+06" maxx="1.11456e+06" maxy="7.94045e+06" /> 

- <Style>

  <Name>default</Name> 

  <Title>default</Title> 

- <LegendURL width="20" height="15">

  <OnlineResource xmlns:xlink="http://www.w3.org/1999/xlink" xlink:type="simple" xlink:href="http://adaptiveutv.avinet.no/wms.aspx?version=1.1.1&service=WMS&request=GetLegendGraphic&layer=layer_74&format=image/png" /> 

  </LegendURL>

  </Style>

  </Layer>

 

 

Now I am connection to some other external WMS service that use ARCIMS, and I can see there that the SRS (EPSG code) is not put on each layer, but on the ?service level??

 

My question is: What is the correct way of dooing this according to the WMS standard? Should each SRS be on each layer or on the ?service level?? 

 

 

Best regards
