Hi all, I want to make wcs:GetCoverage for EPSG:3857 imagemosaic layer via WPS for 2 band geotiff with enabled time dimension. I need to make it via xml because it is subprocess that I then pass to another WPS process. I want to do trimming on X,Y and slicing on time dimension. I figured out that trimming on X, Y doesnt work properly, in example provided I removed time slicing from xml.
I am able to successfully make request using URL, example: http://$myhost/wcs?service=WCS&version=2.0.1&request=GetCoverage&CoverageId=$mylayer&subset=time%28%222018-07-05T18%3A28%3A49Z%22%29&subset=Y%28%226624142.1205998%22%2C%226627044.61116465%22%29&subset=X%28%22-12634038.6283464%22%2C%22-12631578.4675999%22%29&subsettingcrs=http%3A//www.opengis.net/def/crs/EPSG/0/3857&format=geotiff - works fast and makes what I need. Nevertheless, when I try to make the same request with wps xml based, i have Failed to read the coverage $mylayer org.geotools.referencing.operation.projection.ProjectionException: Latitude 6538310°55.6&apos;N is too close to a pole. My XML is: <?xml version="1.0" encoding="UTF-8"?> <wcs:GetCoverage xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation="http://www.opengis.net/wcs/2.0 http://schemas.opengis.net/wcs/2.0/wcsAll.xsd"; xmlns="http://www.opengis.net/wcs/2.0"; xmlns:wcs="http://www.opengis.net/wcs/2.0"; xmlns:wcscrs="http://www.opengis.net/wcs/crs/1.0"; xmlns:geotiff="http://www.opengis.net/gmlcov/geotiff/1.0"; service="WCS" version="2.0.1"> <wcs:CoverageId>$mylayer</wcs:CoverageId> <wcs:trimDimension> <wcs:dimension>X</wcs:dimension> <wcs:trimLow>-12634495.04</wcs:trimLow> <wcs:trimHigh>-12631901.29</wcs:trimHigh> </wcs:trimDimension> <wcs:trimDimension> <wcs:dimension>Y</wcs:dimension> <wcs:trimLow>6682245.66</wcs:trimLow> <wcs:trimHigh>6684794.46</wcs:trimHigh> </wcs:trimDimension> <wcs:format>image/geotiff</wcs:format> <wcs:Extension> <wcscrs:subsettingCrs>http://www.opengis.net/def/crs/EPSG/0/3857</wcscrs:subsettingCrs> <wcscrs:outputCrs>http://www.opengis.net/def/crs/EPSG/0/3857</wcscrs:outputCrs> </wcs:Extension> </wcs:GetCoverage> I tried different combinations of wcscrs:subsettingCrs/wcscrs:outputCrs - hasn't helped yet. I understand that the issue is about axises in 3857 projection, and I read all the posts on the forum about that. But I am still not able to make valid WPS/XML-based request.
