<p class="MsoNormal"><span lang="EN-US" style="mso-fareast-language:EN-US">The wgs84-BoundingBox is an optional element in the CoverageSummary by the WCS 2.0.1 standard. There may be no way to configure Mapserver to add that information into GetCapabilities.
You must read extents coverage by coverage with DescribeCoverage requests. But the boundedBy in that place is using the native CRS of the coverage like here:<o:p></o:p></span></p>

could be useful for WCS clients but even the GetCapabilities example in the WCS Core 2.0.1 standard does not contain it.<o:p></o:p></span></p>

<p class="MsoNormal">Hi,<o:p></o:p></p>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">A week and a half ago I asked about using Mapserver +WMS to serve elevation data since I was following a tutorial that discussed WMS.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">In one of the replies I received, Jeff suggested that I actually wanted WCS for my use case which was a forehead slap + d'oh! moment for me. Of course I do!<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">Anyway, I have followed the Mapserver WCS docs and everything seems to work well.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">However, I have one question that may be kind of niche or will perhaps betray my overall ignorance.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">A while ago I wrote a WCS client for another project and it expects WCS version 2.0 requests.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">The map file that I made up (based closely on the one in the docs: <a href="https://mapserver.org/ogc/wcs_server.html#example-wcs-server-mapfile">https://mapserver.org/ogc/wcs_server.html#example-wcs-server-mapfile</a> ) seems to work fine
for WCS 1.0, 1.1, and 2.0. However, I don't seem to get a bounding box from GetCapabilities in the CoverageSummary from my 2.0 requests whereas I certainly do from the 1.1 request:<o:p></o:p></p>
