Re: [mapserver-users] Getting started with WCS on mapserver...
Hi Jukka, Thank you for the explanation. I will see about using DescribeCoverage instead. I just tried it with my server and the gml:Envelope is indeed filled in properly and I should be able to use it. carl On Mon, Oct 18, 2021 at 11:49 AM Rahkonen Jukka (MML) < jukka.rahko...@maanmittauslaitos.fi> wrote: > Hi, > > > > The wgs84-BoundingBox is an optional element in the CoverageSummary by the > WCS 2.0.1 standard.

Re: [mapserver-users] Getting started with WCS on mapserver...
Hi, 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: http://www.opengis.net/def/crs/EPSG/0/3067; axisLabels="x y" uomLabels="m m" srsDimension="2"> 212000 6762000 218000 6768000 The extent that appears in DescribeCoverage can be configured with the “wcs_extent” metadata if it does not get generated automatically right. Having wgs84-BoundingBox in CoverageSummary could be useful for WCS clients but even the GetCapabilities example in the WCS Core 2.0.1 standard does not contain it. -Jukka Rahkonen- Lähettäjä: MapServer-users Puolesta Carl Godkin Lähetetty: maanantai 18. lokakuuta 2021 21.24 Vastaanottaja: mapserver-users@lists.osgeo.org Aihe: [mapserver-users] Getting started with WCS on mapserver... Hi, 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. 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! Anyway, I have followed the Mapserver WCS docs and everything seems to work well. However, I have one question that may be kind of niche or will perhaps betray my overall ignorance. A while ago I wrote a WCS client for another project and it expects WCS version 2.0 requests. The map file that I made up (based closely on the one in the docs: https://mapserver.org/ogc/wcs_server.html#example-wcs-server-mapfile ) 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: I get this from VERSION=1.1.0: bathymetry -180 -90 180 90 urn:ogc:def:crs:EPSG::4326 image/tiff bathymetry whereas I get just this from VERSION=2.0.1: bathymetry RectifiedGridCoverage Is there something I can add to my WCS map file to get the "ows:WGS84BoundingBox" element returned in my GetVersion? I believe I was working with Geoserver sources when I wrote that client but I would really like to get the geographic extents.
