Hi, Hi,
I do not know how QGIS deals with this, but how about using VRT? It is XML and you can use it with GDAL tools. Try Step 1. gdal_translate -of vrt WCS:"http://demo.geo-solutions.it:80/geoserver/wcs?version=2.0.1&coverage=sf__sfdem"; wcs.vrt Step 2. gdal_translate -of GTiff -outsize 200 200 -projwin 589980.000 4928010.000 590980.000 4918010.000 wcs.vrt converted_from_wcs_vrt.tif This VRT file did not work with my QGIS but a VRT created for my local Geoserver works. Steps to follow gdal_translate -of VRT WCS:"localhost:8080/geoserver/wcs?version=2.0.1&service=WCS&coverage=sf__sfdem" localwcs.vrt QGIS opens localwcs.vrt. The VRT file is referencing another XML file that is created by the WCS driver, in my case <SourceFilename relativeToVRT="0">C:\Users\JRAHKONEN\.gdal\wcs_cache\DokaJ.xml</SourceFilename> QGIS was not able to open C:\Users\JRAHKONEN\.gdal\wcs_cache\DokaJ.xml directly but I did not spend much time for finding out why not. So if you want to continue the game: 1. create vrt with gdal_translate 2. check what xml file it is reading 3. move the xml file away from the WCS cache directory 4. edit the vrt file and update the reference into the XML file 5. Try with GDAL tools and QGIS. I am not at all sure if QGIS can use the WCS-VRT layer in a way that makes sense. I suggest to test with your own Geoserver and follow what kind of requests QGIS creates. Good luck. -Jukka Rahkonen- -Jukka Rahkonen- Lähettäjä: 1520 gis <juliermeopensourcedevelo...@gmail.com> Lähetetty: maanantai 23. marraskuuta 2020 16.01 Vastaanottaja: gdal-dev@lists.osgeo.org; Rahkonen Jukka (MML) <jukka.rahko...@maanmittauslaitos.fi> Aihe: Re: gdal-dev Digest, Vol 198, Issue 45 Dear Rahkonen Jukka, I will consider your warnings about using GDAL_WCS with GeoServer. It seems that what I am trying to do is not possible, but it will be something interesting to achieve through GDAL_WCS. In many cases, the user has access to wcs geoservices and he may be interested in loading some specific coverages (full coverage and subsets) in QGIS using an XML just like GDAL_WMTS driver. Some institutions make WCS capabilities available, but wmts. And this is my situation, I have a remote / external geoserver with wcs capabilities available, but wmts. It could be something interesting to be implemented in the future. Thank you very much for your time and consideration of my messages.

It seems to be related with the native CRS EPSG:4326. So if you test now with Geoserver, don't test with nurc__Img_Sample or other coverages which are in EPSG:4326. I know this does not answer your question, sorry. -Jukka Rahkonen- juliermeopensourcedeveloper wrote > Dear all, > > I would like to open this discussion here about creating a xml/ raster wcs > ingest using gdal_translate. > My 2 goals are: > 1 - get a xml like in [1] by running command line similar do gdal_wmts > driver in [2] > > gdal_translate "WCS: > http://demo.geo-solutions.it:80/geoserver/wcs?version=2.0.1&coverage=nurc__Img_Sample > <http://demo.geo-solutions.it/geoserver/wcs?version=2.0.1&coverage=nurc__Img_Sample> > " wcs.xml -of WCS > > *OR* > > gdal_translate "WCS: > http://demo.geo-solutions.it/geoserver/ows?service=WCS&request=getCapabilities,layer=nurc__Img_Sample > " wcs.xml -of WCS > > > 2 - get a xml / raster subset > > gdal_translate "WCS: > http://demo.geo-solutions.it:80/geoserver/wcs?version=2.0.1&coverage=nurc__Img_Sample > <http://demo.geo-solutions.it/geoserver/wcs?version=2.0.1&coverage=nurc__Img_Sample> > " wcs.xml -projwin -100 40 -80 30 -of WCS > > *OR* > > gdal_translate "WCS: > http://demo.geo-solutions.it/geoserver/ows?service=WCS&request=getCapabilities,layer=nurc__Img_Sample > " wcs.xml -projwin -100 40 -80 30 -of WCS > > If the solution I am trying to get can not be possible through > gdal_translate, would someone have an xml sample like in [1] to share, but > with raster subset ingest, instead the whole image content? > > I appreciated your time in advance. > > Kind regards > > Julierme > > [1] > <WCS_GDAL> > > <ServiceURL> > https://demo.geo-solutions.it/geoserver/wcs?version=2.0.1& > ; > </ServiceURL> > > <CoverageName> > nurc:Img_Sample > </CoverageName> > > <GetCoverageExtra> > &BoundingBox=-130.85168,20.7052,-62.0054,54.1141 > </GetCoverageExtra> > </WCS_GDAL> > [2] gdal_translate "WMTS: > http://maps.wien.gv.at/wmts/1.0.0/WMTSCapabilities.xml,layer=lb"; wmts.xml > - > of WMTS. > > _______________________________________________ > gdal-dev mailing list > gdal-dev@.osgeo<mailto:gdal-dev@.osgeo> > https://lists.osgeo.org/mailman/listinfo/gdal-dev -- Sent from: http://osgeo-org.1560.x6.nabble.com/GDAL-Dev-f3742093.html ------------------------------ Message: 3 Date: Sat, 21 Nov 2020 09:59:01 -0500 From: Franco Amato <cvfr...@gmail.com<mailto:cvfr...@gmail.com>> To: gdal-dev@lists.osgeo.org<mailto:gdal-dev@lists.osgeo.org> Subject: [gdal-dev] Automatic labels placement Message-ID: <cadaawmcjmh6hs6hm1wkgjykmjzxetgqywrsokfrw3e1lucg...@mail.gmail.com<mailto:cadaawmcjmh6hs6hm1wkgjykmjzxetgqywrsokfrw3e1lucg...@mail.gmail.com>> Content-Type: text/plain; charset="utf-8" Good morning gdal members, I would know if you know any automatic labels placement library.
